47. Mila Kunis & Macaulay Culkin
Ever since men started drooling over her in Forgetting Sarah Marshall, Kunis' popularity has skyrocketed, and her resume proves it: She has three movies on her plate for 2010, and she's still getting regular paychecks from Family Guy. Macaulay has never returned to his glory days of child acting (he was making about $8 million per film) but he did appear in a few episodes of the TV series Kings in the past year. They've been dating since 2002.
