We're used to seeing Kate Winslet [1] in more serious roles on the big screen, but the Oscar winner showed off her sillier side during an appearance on The Tonight Show this week. On Wednesday, Kate played a game of Photo Booth with Jimmy Fallon [2]; the two took turns trying to take the funniest, most unattractive selfies with the iPad app and its many effects, and Kate's entries were surprisingly hilarious. We've gotten a glimpse of her lighthearted attitude quite a bit this week. Kate rang in her 40th birthday on Monday and celebrated by posing for a few candid paparazzi snaps [3], even holding up a "40" sign with her fingers for the cameras. The following day, Kate and her husband, Ned Rocknroll [4], were spotted leaving their NYC hotel hand in hand. Watch Kate's foray into comedy above now.
