Ryan Phillippe – Baby #3?

Ryan Phillippe might be getting ready to be a dad again!  The actor’s ex-girlfriend, model Alexis Knapp, says she’s carrying his baby.

A source close to Alexis tells UsMagazine that she’s in her second trimester.   Alexis and Ryan dated for several months on and off last year before he ended the relationship in September.  An insider says, “Ryan doesn’t know if he is the dad.  If he is, he will take full responsibility for the child.”

Ryan already has two kids with ex-wife Reese Witherspoon (Ava, 11, and Deacon, 7).  Ryan is currently dating Amanda Seyfried.
