Is the "Baywatch" babe expecting?

PAMELA ANDERSON and RICK SALOMON, who recently filed for a marriage license in Las Vegas, could possibly be parents soon -- according to OK! magazine.

A source tells OK! that the actress "definitely looks like she's got a bit of a bump," and that "this wouldn't be the first time Pam has rushed off to get married because there's a baby coming."

According to the magazine, the source is referring to the rumors that Anderson married her ex KID ROCK in 2006 because she was pregnant -- a claim that has been denied by the actress.
