Mila Kunis got pretty candid about her sex life on Monday's episode of The Late Late Show when she played a game of "Spill Your Guts or Fill Your Guts" with host James Corden. Corden asked Kunis to describe her husband Ashton Kutcher's penis during the game and rather than drink a glass of clam juice, Kunis fessed up, describing it as a Guinness beer can. When later asked how Ashton took the news Kunis replied, "He was very happy about the Guinness."
