Couple News: Mariah & Eminem?

Are snarly rapper Eminem and girly singer Mariah Carey an item?

A reported "secret meeting" between the polar-opposite music celebs is being blown into a full-fledged romance by several gossip-slingers, who say that Carey's three-year romance with Luis Miguel is now in danger. Maybe Eminem just wants to make a Dido-like music connection with the sexy songstress. Or it could be that they're comparing notes on breaking into acting … both the Detroit native (real name Marshall Mathers) and Carey, who hails from the Big Apple, have autobiographical pics headed for the big screen soon.

Alec Baldwin is apparently getting some Sex and the City action after all. The Pearl Harbor star, whose wife, Kim Basinger, left him last year, had announced he's dying to be a guest star on the hot HBO series. He's still a no-show on the Emmy-nominated series, but he was spotted canoodling with Sex's oh-so-proper Charlotte, actress Kristin Davis, at a New York screening of Made. A witness dishes to the New York Daily News, "I'm not sure they saw much of the film because they were all over each other." Another bystander opined to the tab, "They should have left and gotten a room."

Charlize Theron is stepping out with her 24 Hours co-star, Irish actor Stuart Townsend, according to Showbiz Ireland. Theron, who recently split from longtime beau Stephan Jenkins, of Third Eye Blind, and Townsend, who used to date Parker Posey, were spotted at a Bob Dylan concert in Kilkenny, Ireland. The 28-year-old Irishman missed out on movie franchisedom after he was let go from the role of Aragorn in The Lord of the Rings. He'll star as the Vampire Lestat in The Queen of the Damned (which is not going straight to video, as is rumored, but will hit theaters sometime next year, a Warner Bros. rep assures us).
