Look out Liam Neeson, you're about to be out-cameo-ed by former president Bill Clinton.

The 41st president will appear in the Hangover sequel as himself, according to People. The film, which recently experienced some controversy when Mel Gibson was released from his planned cameo slot, is currently shooting in Thailand. Gibson was reportedly booted after cast members objected to his presence on set.

The original movie featured a cameo by Mike Tyson. Sideways star Paul Giamatti has also recently joined the cast, according to Deadline Hollywood. Clinton was scheduled to appear in Bangkok to deliver a speech on clean energy, and dropped in on the set during his time there to film the spot. –AMY LEE
