Chelsea Clinton is embracing public service on a global scale. Bill and Hillary Clinton's 33-year-old daughter, who completed a master of public health degree at Columbia University in 2010, spoke to the media at a women's conference Tuesday in Kuala Lumpur, Malaysia.

She told the Associated Press she plans to work with the Clinton Foundation on projects "related to health . . . around the world." Chelsea recently visited Myanmar as part of an initiative to provide water purification packets to areas with unsafe water supplies. After Malaysia, she'll go to Cambodia to launch an effort to reduce HIV-related deaths. "My goal is always to do as much as I can in whatever area I'm working in," she said.

Will her work give her enough time to raise a family with husband Marc Mezvinsky? "My mother asks me that all the time," Chelsea said, "and anything my mother asks me is fair game."

Henry Cavill: I was fat

It's hard to believe, but Henry Cavill wasn't always the reinforced-steel-abs Studly Do-Right we've come to love from The Tudors and the forthcoming Man of Steel. Hollywood's latest Superman tells USA Today he was a chubby kid.

"I was fat. . . . I was Fat Cavill," he says.

He was motivated to lose more than 20 pounds when cast in a film version of The Count of Monte Cristo at 17.

Cavill had to bulk up big-time to play Superman. "I was a lot bigger. . . . I'm not saying how much. It's modesty about the weight." He's also modest about his gf, MMA bad girl Gina Carano (Haywire), who's rumored to be the next Wonder Woman. "She's amazing" is all he says.

Beyoncé's bod: Not yours to touch!

Beyoncé's a sex symbol who bares her soul (and virtually all her skin) for her art. But don't think that gives the public the right to touch her. A cheeky fan found that out Monday night, when he reached out and smacked B's derriere at a concert in Copenhagen. B, who was in the middle of "Irreplaceable," pointed the guy out to security and picked the song back up as the evildoer was taken out.
