Zach Galifianakis has lost so much weight that he has had to strap on a fake beer belly for his part in The Hangover III.
The popular film series will see Zach reprising his role as the oddball of his friendship group, Alan, starring alongside Bradley Cooper, Ed Helms, Justin Bartha and Ken Jeong in the final episode of the hit comedy.
Seen shooting for some scenes in the film, Zach was more than happy to flash his fake belly for the cameras.
The star revealed on US talk show Live With Kelly last year that his weight slipped off after he stopped drinking, which was a real twist on the films based around the crazy antics that the group of friends encounter thanks to hitting too many boozers.
Earlier this month, the cast were spotting filming a funeral scene in Arizona which doubled for Tijuana, Mexico.
The Hangover III is due for release in May next year.
