Recent Tony nominee and all-around funny guy Will Ferrell, who mooned audiences in Old School and donned a tight leotard for Blades of Glory, celebrates his 43rd birthday today. Did you catch his latest comedy, The Land of the Lost? Yeah, neither did a lot of people. Rumor is, though, he has a cameo in the upcoming Jeremy Piven comedy, The Goods: Live Hard, Sell Hard. A true icon of the '80s, former child star Corey Feldman turns 38. More recently, he starred in an A&E reality show alongside fellow ‘80s heartthrob Corey Haim, entitled The Two Coreys, and the direct-to-DVD sequel, Lost Boys: The Tribe. Another retro favorite, Fast Times at Ridgemont High star Phoebe Cates, who's married to actor Kevin Kline, is 46. 90210 star AnnaLynne McCord turns 22 — last month, she was honored with Hollywood Life's Young Hollywood Superstar of Tomorrow award. Legendary Police drummer Stewart Copeland is 57, and Live frontman Ed Kowalczyk turns 38.
