Ryan's Phillippe's ex-girlfriend, Alexis Knapp, gave birth to a baby girl last Friday, and the actor was by her side throughout.

There were reports that Phillippe would be demanding a paternity test once the baby was born, but US Weekly reports that there's no doubt in the actor's mind that he's the father.

When Ryan Phillippe's ex-girlfriend Alexis Knapp was spotted last week with an obvious baby bump, there was no official confirmation of the speculation that Ryan is in fact the baby daddy.

But Alexis' mother Marjorie Knapp has broken the official silence and tells RadarOnline.com exclusively that Ryan is indeed the father.

"Oh yes, I believe that it is his baby," Marjorie Knapp told RadarOnline.com exclusively. "I'm very proud of her. She did the right thing. She's keeping the baby and not having an abortion.
