Benicio Del Toro, Kimberly Stewart expecting a baby. We kid you not.

Didn't see this one coming.

Kimberly Stewart -- daughter of rocker Rod, friend of Paris Hilton and person not dating Benicio del Toro -- is in fact pregnant with del Toro's baby. A publicist for the actor confirmed the news to Life & Style.

"Kimberly is pregnant. Benicio is the father and is very supportive," del Toro's publicist said. "Although they are not a couple, they are looking forward to the arrival of the baby."

Okay. We haven't been surprised since we found out that Tom Cruise knocked up Katie Holmes.

Stewart, 31, has previously been linked with British actors Jude Law and Rhys Ifans. Del Toro, 44, has -- until now -- managed to keep his private life under wraps.
