Zach Galifianakis poses in swimsuit

Zach Galifianakis has posed in a women's swimsuit for the new issue of Vanity Fair.

The Hangover star donned a pink bathing suit for a spoof feature called 'The Zach Galifianakis Swimsuit Calendar', which showed him posing in the one-piece on a beach in a variety of positions.

The actor also joked to the magazine about working with Robert Downey Jr. on the upcoming Due Date, saying: "He told me in front of 45 extras that I needed acting classes. I like to call him 'another Irish mistake'."

Galifianakis is currently filming The Hangover 2 in Vancouver with Bradley Cooper, Justin Bartha and Ed Helms, and recently teased that fans could expect a "better" movie than its award-winning prequel.
