(Cover) - EN Showbiz - Bill Clinton will make a cameo appearance in The Hangover sequel, it has been reported.

The former US President is believed to have filmed his scenes over the weekend in Bangkok, Thailand.

In the first film, a group of men went to Las Vegas for a wild bachelor party, and a series of bizarre events occurred. The Hangover Part II is set to be just as outrageous, as Bradley Cooper, Ed Helms and Zach Galifianakis reprise their roles.

Clinton, who'll play himself in the comedy, shot his brief appearance on Saturday in Bangkok, where part of the production takes place. He was in the capital city to deliver a speech on clean energy, People magazine reports.

Todd Philips directed the first movie and will also helm the sequel.

Former boxer Mike Tyson is rumoured to be making another appearance in the follow-up film, while troubled Hollywood actor Mel Gibson was initially set for a cameo role as a Bangkok tattoo artist. However, members of the cast and crew were reportedly unhappy with his involvement, so his part was later filled by Liam Neeson. (C) Cover Media
