Mark Wahlberg, the uber bad boy nearly cast in Brokeback Mountain, turns 36 today; more famous births here. Wahlberg was considered for the role that ultimately went to Jake Gyllenhaal. But he backed out, unnerved by the sex scenes. (No doubt not explicit enough. Huh!) Guess all those Brokeback shopping lists would've included tighty-whities. Owen Wilson -- rumored to have been spotted recently at Bi-Rite Creamery -- has split from Kate Hudson. Want more Wahlberg? Here's a way-old video -- a good thing! This is from his underwear modeling days -- showing a Calvin Klein shoot by photographer Annie Leibovitz.
