Actors Matt Damon (L) and George Clooney

Matt Damon revealed on Tuesday night’s episode of ‘The Tonight Show with Jay Leno,’ he was pranked by George Clooney! While filming, “Monument’s Men,” out February 7th, Clooney got Damon’s pants sized smaller every few days that made Damon think he was starting to gain weight. What makes this even better is the two of them had made a previous agreement to ‘get in shape.’ Damon had no idea he was being pranked until after he read about it after filming was completed! Listen to what Matt Damon had to say about it below!
