After a hilarious and unpredictable evening, celebs headed to the exclusive MTV after party and one star even stepped out with her new beau!

After Robert Pattinson and Taylor Lautner‘s make out session and Reese Witherspoon‘s shocking speech, A-list guests partied the night away! Rob and Kristen Stewart opted to ditch their red carpet garb for jeans and t-shirts and head to the Chateau Marmont before hitting up Soho House for the real fun!Also at the party was Horrible Bosses star Jennifer Aniston with her rumored new man Justin Theroux! The two stayed together the entire evening and at one point you could even see Jen keeping her eye on Justin while he chatted with host Jason Sudeikis!

Harry Potter star Emma Watson looked adorable as she mingled with partygoers and even posed for a picture with Cameron Diaz! Cameron was thought to be broken up with NY Yankees star Alex Rodriguez but the two reportedly left holding hands!

Taylor Lautner and his girlfriend Lily Collins cozied up to one another and hung out with Emma. And Chace Crawford stopped by, dressed super low key — he must be tired from his sister’s wedding festivities that took place to Dallas Cowboys star Tony Romo last week!

It was a night to remember — ain’t no party like a West Coast party!
