Angelina Jolie & Brad Pitt: '12 Years' Dinner with Lupita Nyong'o!

Angelina Jolie and Brad Pitt attend a dinner for his movie 12 Years a Slave on Saturday evening (March 1) at Sunset Tower in West Hollywood, Calif.

The engaged couple was joined by his co-stars Lupita Nyong’o, Chiwetel Ejiofor, Michael Fassbender, and director Steve McQueen. The cast was not only celebrating their film at the dinner – it was also Lupita‘s 31st birthday that day!

Earlier in the day, Brad and Angie attended the 2014 Independent Spirit Awards where the film won a bunch of awards including Best Feature. After the show, the couple was seen leaving and Angie almost tripped over her dress, but she was saved by Brad!

FYI: Lupita is wearing a Jonathan Cohen dress, Paul Andrew shoes, an Edie Parker clutch, and Dana Rebecca Designs jewelry. Angie is wearing a Saint Laurent dress, shoes, and bracelet.
