Who's Your Daddy? Kimberly Stewart is Expecting a Baby with Benicio del Toro

If you've wondered where actor Benicio del Toro has been for the last few years (and you didn't see "Che"), we've got your answer.

He's been busy making whoopee with Kimberly Stewart (Paris Hilton gal-pal and daugter of rock legend Rod Stewart.)

Del Toro's rep, Robin Baum, tells Life & Style magazine that "Kimberly is pregnant. Although they are not a couple, they are looking forward to the arrival of the baby."

Sweet. So the duo never dated, don't plan on dating, but they are pumped about having a kid? So Hollywood of them.

They have never been photographed together so either this baby was conceived during a top secret relationship or, more likely, during a one-night stand.

The socialite has been engaged twice before; once to rocker Cisco Adler and once to fellow rich kid Talan Torriero. Although she never married either, we give her props for trying.

Del Toro, who is stepping up to the plate as dad, has signed on for a number of upcoming films. He will begin production on "The Iceman" and "Savages" in the months to come. Hey, someone's got to start the college fund.

Being the first child for both parties, we send them congrats and wish them well!
