By
Cameron Diaz co-stars withreal-life exJustin Timberlake in 'Bad Teacher,' in theaters June 24, and the pair clearly had such a blast making the movie, it's a wonder they made it through every scene!
Watch the video outtakes as Cameron and Justin try to keep a straight face in several different takes – and who knew Cameron was a snorter? The star breaks down entirely during a scene in which she has to hold a corn dog with mustard…
In 'Bad Teacher,' Cameron plays Elizabeth, a teacher who couldn't care less about her grammar school job -- and does little to hide it. But when a rich, handsome substitute teacher (Justin) enters the picture, Elizabeth sets her sights on manipulating him into marriage, going to extremes to win him over.
