How do you celebrate a BAFTA Award  win? With a star-studded afterparty, of course. Brad Pitt , Angelina Jolie , Oprah, and Lupita Nyong'o were just a few of the famous faces who attended sparkling fetes following the BAFTA Awards in London on Sunday night. Angie, Brad, and Lupita toasted to 12 Years a Slave's best picture win at E One and Grey Goose's bash, while Harvey Weinstein hosted Oprah, Naomi Campbell , and Cate Blanchett  (among others) at his own separate post-BAFTAs party. Brad and Angie were still rocking their sexy matching tuxedos  from earlier in the night while they held court with British rapper Tinie Tempah. Meanwhile, Oprah couldn't resist having fun with Naomi, Harvey's wife, Georgina Chapman, and Rita Ora.
One person who wasn't at any of the afterparties was Prince William, who made a special appearance at the BAFTA Awards  earlier that night to present an award to Helen Mirren .
