Bruno Mars, Paul McCartney, Chelsea Handler & More Hit Grammy After-Party (PHOTOS)

Celebs flocked to Warner Music Group’s Grammy Celebration hosted by InStyle at Chateau Marmont on Sunday following the awards show. Bruno Mars gave a show stopping performance with his band outside on the patio that had the star studded crowd on their feet.

Chelsea Handler even hoisted herself up on one of the tables outside to get a better look! Handler was in attendance with ex boyfriend Andre Balazs…are the duo back on? We’re told they certainly looked like it!


Lana Del Rey was also in attendance at the bash, and held court outside keeping a low profile. The singer, who received a lot of backlash following her SNL performance, seemed shy almost hanging with a few people from her team.

Paul McCartney made a late entrance at the famed hotel arriving after midnight and held court outside with security in tow.

A newly single Chord Overstreet was also in attendance but hung out mostly solo aside from chatting with costar Matthew Morrison for a bit.

Fergie, Blake Shelton and Kelly Clarkson rounded out the A List party.
