Ryan Phillippe`s ex welcomes baby girl

London: Actor Ryan Phillippe`s ex-girlfriend Alexis Knapp has given birth to a baby girl.

The model-actress, who claimed Phillippe is the father of the baby, welcomed Kai, last Friday, and the actor was reportedly by her side throughout the birth. "He is a good father and whether this is his baby or not, he wants to do the right thing and be supportive. Knapp is really excited to be a mom," contactmusic.com quoted a source as saying. It has not yet been confirmed whether Phillippe is the father of the baby. He is expected to undergo a paternity test in the coming weeks. The 36-year-old dated Knapp on-and-off for several months until September 2010. IANS
