This is a TVD crossover with Gossip Girl – this site just wouldn't give me the option to mark it so.

Dedicated to my Klarobesties (and Klarochair lovers, like me) Kaitlyn and Erika, who are incredible human beings for doing 60 days of sacrificing sugar with me. I literally wouldn't have been able to get throught it otherwise so thank you guys so much :)

Hayley doesn't exist and never did.

Enjoy :)

Caroline signed her name in the guest register book then smiled down at it, amused, before looking up at the man behind the desk.

He nodded and she grinned giddily before stepping back and into the hall.

For a second she stood stock still, admiring the people, music, food and general glamour.

She still couldn't believe she was actually here. It had always been a dream of hers to come to New York – see Fashion Week and attend all the parties; rub shoulders with the elite and use fancy words in long important toasts.

And here she was, with everything right in front of her. The only thing missing was Fashion Week, which she'd stupidly missed being held up in Mystic Falls, but luckily there was still some fashion involved in this party, being the celebration of a designer's successful new line.

She couldn't wipe the smile from her face as she took a seat at the table where her name was engraved into a silver name plate beneath Waldorf Designs.

Lifting it, she ran a finger over the cool metal, staring at the name she'd picked for herself in this city.

Caroline Mikaelson

It had all happened so suddenly – she'd been compelling her way into this party when the man asked for her name and she panicked, realising that if anyone did a proper background check on Caroline Forbes, they'd know she didn't belong here.

The first thing that had come to mind was impersonating someone – someone who had never been here before but would have an impressive record. Rebekah Mikaelson, she'd almost said. But she had no way of knowing if Rebekah had in fact been here and made enough of a name for herself to be recognised, which would put Caroline in hot water.

She ran a finger over the stolen surname, thinking about what it implied.

"Hey. Would you like to dance? I've suddenly found myself minus a date."

Caroline looked up and came face to face with an insanely cute guy. He had light brown hair, dreamy eyes and impossibly deep dimples.

"I'm Nate, by the way," he smiled.

"Caroline," she grinned, about to stand up and accept his offer.

"No offense, mate, but I think my offer is slightly more tempting."

Caroline froze at the familiar voice and her heart jumped into her throat when from behind Nate stepped a man who had his own set of dimples and dreamy eyes.

Thinking quickly, she put the name plate back on the table, upside down.

Klaus offered his hand and she took it, standing up.

"Sorry," she smiled apologetically at Nate.

"No problem," he replied, though he looked confused, like no one had ever rejected an offer like that before.

Klaus led her out onto the dance floor before pulling her into him as they began dancing, a smirk set on his face.

"Don't look so smug," she glared. "I only came out here with you so I could find out what the hell you're doing here."

He looked amused. "The more things change, the more they stay the same."

She frowned, confused, before she realised what he was referring to.

I'm not talking to you until you tell me why you invited me here.

Huffing, she decided to change tactics.

"I'm guessing you compelled your way in?"

"As much as you did," he smirked. "I could have obtained an invitation but it was quite a last minute decision."

"Why, because you're stalking me?"

He chuckled. "That's a bit harsh, love. I was simply intrigued by what it is you're doing in New York."

"Did you follow me here?"

He spun her and she watched the room whirl, a sea of glitter and lights. Her dress fanned out around her for the few seconds before he pulled her back in.

"Have I mentioned how ravishing you look?"

Caroline blushed.

She'd spent forever picking out the dress, wanting her first impression to be a good one and she'd ended up picking a perfect one if she said so herself. It was a pale beige, the bodice encrusted and sparkling everywhere, leading down to where it flared out from her waist right down to her knees. She'd paired it with nude Manolos.

"Thank you," she breathed, reluctantly. "You don't look so bad yourself."

He looked pleased by the semi-compliment, smirking, and she rolled her eyes.

The song was winding down.

"How long are you staying for?" she asked, watching his reaction closely.

But it was casual and accompanied by a small shrug, a mark of honesty with him, she'd learned.

"Haven't quite decided yet."

She gritted her teeth. "Is it going to depend on how long I stay for?"

He smiled, looking charmed; his dimples deep. "Perhaps."

She stopped as the song did, pulling her hand from his.

"Just stay out of my way, Klaus, ok?"

"Let me guess: already spoken for?"

The words caught her by surprise and a smile escaped before she could help it.

She recovered quickly, glaring at him instead.

"Seriously. Stop… showing up."

With that she turned around and made a beeline for wherever the ladies' room was, knowing that was at least one place he wouldn't be able to follow her into.

Caroline stared at herself in the mirror.

Considering she'd only been here for about fifteen minutes there wasn't really anything to fix so instead she stared into her own eyes, trying to figure herself out.

If she'd seen pure annoyance and frustration behind the blue orbs rimmed by black eyeliner and darkened lashes, she wouldn't have spared another glance.

But her eyes glittered and her lips lilted a little at the sides, no matter how much she tried to straighten them out.

Something about seeing Klaus had shaken her up and not in the way she would've expected.

Hearing someone approach the ladies' room, she took a deep breath and told herself that she'd just been surprised and hadn't totally hated it because it had been nice to see a familiar face in a strange place.

Satisfied, she smiled at herself as a woman pushed inside, looking annoyed.

She was beautiful, a brunette with huge expressive eyes and pert lips, and she wore a gorgeous deep red floor-length gown.

Ignoring Caroline, she dropped down into an armchair and lifted her dress with a frustrated puff of air.

The woman looked strangely familiar even though Caroline knew she'd never met her. She stepped forward curiously.

"Hi. Is something wrong?"

The brunette looked up then rolled her eyes. "My best friend met a guy here and decided to go somewhere with him in the middle of my party and being the amazing friend that I am, I decided to see her off at the airport. Which was great for us but completely ruined my shoes."

Caroline looked down at where the woman was removing her heels. They were Louboutins and a thin coat of grime that was clearly not supposed to be there covered the light material.

"Wait," Caroline frowned. "Your party?"

The woman removed her shoes with a sigh. "I guess technically my mother's hosting it but it's for me." Looking up at Caroline again, she stretched out a hand. "Blair Waldorf, I don't believe we've met."

Caroline's eyes widened. "No, no we haven't. I'm Caroline, uh, Mikaelson."

"Caroline, you wouldn't happen to have a spare pair of heels, would you?" Blair joked, holding up a pair of flats. "These are the only spare shoes I brought, for after."

Caroline's brow furrowed. "You have to wear heels with that dress."

"Exactly," Blair moaned, looking down at her shoes as she pondered the situation.

"What size are you?"

"Six."

"Me too! Here, let's swap," Caroline smiled, sitting down opposite Blair.

"Are you sure?" the brunette asked.

"Yeah. I mean, this is your party, you can't exactly go out there in flats."

"What are you going to wear?"

The blonde pulled a face as she removed her Manolos. "I was thinking of going home anyway."

"You don't like the party?"

"No!" Caroline replied hastily. "I just… saw someone and it rattled me a little."

"Ex?"

She hesitated. "Something like that."

Caroline held out her nude heels and Blair smiled.

"Well thank you, Caroline Mikaelson. You are a lifesaver," she said, taking them and passing Caroline the flats.

"No problem." She frowned as she pulled on the other woman's shoes. "Did you just say that your friend just met someone at the party tonight then went to another country with him?"

Blair smirked. "I know it sounds strange but trust me, I would be worried if it were actually out of character for her."

Caroline laughed. "Ok." She stood. "I should go."

She shot herself one last glance in the mirror and grabbed her purse, making to leave.

"Caroline!" Blair called and Caroline turned back around. "Personally I think you should go out there and dance with the cutest guy you can find to show this other guy exactly what he no longer has," Blair smiled slyly as she pulled on the shoes, "but if you do want to go home, you can take the limo I have waiting for me."

Caroline gasped. "What? No! Seriously, I'm ok, I was just going to take a cab."

"Come on, I practically just stole your shoes – I owe you a ride."

Caroline opened her mouth to refuse once more but the brunette shook her head vehemently.

"Go outside, ask for Arthur and say I told him to take you home. Then ask him for my address so you can get your shoes back tomorrow."

Caroline's jaw hung open. This woman was even more bossy than she was.

She liked her already.

"Fine. Thank you."

Blair smiled. "Don't thank me – you just saved me in a shoe emergency, I'm pretty sure I'll remember you on my deathbed."

Both women laughed before Caroline exited the bathroom with a small nod. Outside she grinned, giddy with the fact that she was about to have her first limo ride.

Blair stood, facing the mirror as she checked her makeup. She didn't care too much about the party considering her mother hadn't even been able to make it and she could've easily sent for a pair of heels from her own closet if not for what she did care about – Chuck.

He'd thought he'd be unable to make it but had managed after all and was now out on the dance floor waiting for her. And considering they weren't allowing themselves so much as kissing, Blair was going to dance with her Bass if it was the last thing she did.

Satisfied with her makeup, she lifted her dress to look down at the borrowed shoes.

They were nude and matte, exactly what she would have chosen to pair with the dress the blonde had been wearing if it had been her.

She'd never heard of the woman before, which was strange, but obviously it was someone her mother knew if she'd invited her to the party, which was half why she'd been so nice to her. The other half being that she hadn't actually seemed that bad and had definitely skyrocketed in Blair's esteem when she offered up her shoes.

Blair shifted her weight to make sure the shoes fit perfectly before letting the dress back down and picking up her purse.

Blair had two thoughts on her mind as she exited the bathroom. The first was Chuck, of course, accompanied by all the usual thoughts – the ring that hung around her neck and the determination for both of their success.

But the second was more surprising, intriguing even.

She quite liked Caroline.
