Brad Pitt and Angelina Jolie enjoyed a relatively public date last night at the 30th Anniversary of the Museum of Contemporary Art in Los Angeles.

The couple had their "serious art faces" on for much of the event, gazing thoughtful at the artwork.

But this frame caught Angelina in a more lighthearted mood -- guess she's not letting the impending release of Ian Halperin's tell-all get her down!
