Brad Pitt was surrounded by fans as he made his way into the Screen Actors Guild to participate in a Q & A on Moneyball with costar Jonah Hill in LA this afternoon. He was casual in a sweater and glasses by Dolce & Gabbana after donning a sexy tuxedo at last night's Golden Globe Awards. Brad made a grand entrance with Angelina Jolie, who wore a stunning white Atelier Versace gown by his side on the carpet. They both took the stage to present with Brad introducing pal George Clooney's The Descendants, which ended up winning best picture, and Angelina giving away the statue for best director. Neither Brad nor Angelina took home the awards they were nominated for, but the couple did continue the fun by attending an afterparty at Sunset Tower.
