(LOS ANGELES) -- Ryan Phillippe may become a father again. The 36-year-old actor already has two children with ex-wife Reese Witherspoon, and now word is that his ex-girlfriend, pregnant model-actress Alexis Knapp, is claiming that she's carrying his baby.
A source close to Knapp confirms to UsMagazine.com, "She's in the second trimester." However, a Knapp source said, "She's not commenting on who the father is."
Phillippe dated Knapp for a few months on and off last year before he broke it off in September. He's currently dating actress Amanda Seyfried.
Knapp's next film is the Miley Cyrus comedy So Undercover, which is out in October, followed by Project X in November.
