Kate Upton Got A Mustache Drawn On Her In Evil Prank

Cameron Diaz and Leslie Mann were guests on "Late Night with Seth Meyers" Thursday, April 24, and shared a hilarious story of bonding while filming their movie "The Other Woman." On a flight they took with co-star Kate Upton, they told Meyers, Upton fell asleep as soon as they took off. The juvenile pranksters in them took charge, and the two blondes decided to draw a mustache (and a tiny beard!) on the supermodel's face.

Diaz then explained that she felt so bad. "I was like, 'We can't take pictures unless we have mustaches as well.' So we have other pictures where we're drawing on each other's faces," she said, laughing.

Though Mann wanted to leave the artwork on Upton's face so that she woke up with it, Diaz insisted on wiping her clean.




Conclusion No. 1: Kate Upton is a very heavy sleeper. Conclusion No. 2: Never fall asleep around Leslie Mann and Cameron Diaz.

"The Other Woman" is out in theaters now.
