Ryan Phillippe could become a dad for the third time. Sources confirmed reports that his former model and actress girlfriend, Alexis Knapp, has told friends she’s expecting his child. One said, “Knapp says she is pregnant, but it has not yet been fully confirmed it’s Ryan’s baby. But if it is his child, he will of course do the right thing and take full responsibility for the baby.” Phillippe already has two kids with ex-wife Reese Witherspoon. He was recently involved in an on-off romance with “Red Riding Hood” star Amanda Seyfried. His rep declined to comment.
