Ryan Phillippe may have to dial Maury Povich for help now that one of his former flings is pregnant and he is the rumored father. The actor briefly dated model-actress Alexis Knapp last year and she was spotted with an obvious baby bump while on a coffee run last week prompting questions about the father of the baby. Knapp, who is in her second trimester, has been telling friends Phillippe is the dad. Ryan already has two children with his ex-wife Reese Witherspoon but sources close to him say he will gladly take a DNA test to determine if he is the father and if he is, he will take full responsibility for the child.
