Reese and Cara are the life of the party!

It was a star-studded evening Jan. 8 at W Magazine’s Best Performances Issue celebration. Joshua Jackson, Diane Kruger, Jamie Dornan, Rosamund Pike, Naomi Campbell and others spent the night dancing, sipping Dom Perignon and taking photo-booth selfies at the pre-Globes bash at the Chateau Marmont in Los Angeles.

Reese Witherspoon, who is nominated for best actress for Wild, was the first to A-lister to stop by right as the party kicked off. She spent her evening mingling with partygoers and happily taking photos with fans.

Before leaving, Witherspoon caught up with another best actress nominee, Amy Adams, and supermodel pal Cara Delevingne, an onlooker tells PEOPLE.

But Delevingne was just getting her night started!

The model gave a few goodbye hugs before running over to Eddie Redmayne and his wife Hannah Bagshawe. She gave the The Theory of Everything actor a big hug and exclaimed, “Oh my god! You’re married! You guys!” an onlooker tells PEOPLE.

Even in a cocktail dress and leather backpack, the model had no problem busting a move at the party.

“They’re strippers!” she joked as a group of fire marshals passed by, the source adds.

The party wound down around some time after 10:30 p.m. as stars said their goodbyes and waved to screaming fans outside.
