Say what you want about Ryan Phillippe’s wandering-eye reputation, but when it comes to parenting, no one can deny he’s a great dad.

So even though he has yet to confirm he’s the father of ex-girlfriend Alexis Knapp’s nearly 2-month-old daughter, Kai, he isn’t wasting any time introducing the baby to his children with Reese Witherspoon, Ava, 11, and Deacon, 7. “Ryan is trying to figure things out, but he believes the baby is his, so he wanted them to meet her,” a pal explains.

While he hasn’t fully explained who Kai is just yet, Ryan, 36, is clearly trying to get a head start on the bonding process.
