Ryan Phillippe was a major newsmaker on Monday -- when UsMagazine.com broke word that the actor, 36, may become a dad again. (Model-actress Alexis Knapp, whom he dated last year, is pregnant and has told pals that he's the dad.)
What did Phillippe have to say about that bombshell during his TV appearance just past midnight on Jimmy Kimmel Live?
Not a whole lot.
Instead, Phillippe gabbed with Kimmel about the kids he already has: Ava, 11, and Deacon, 7, his daughter and son with ex-wife Reese Witherspoon.
The Lincoln Lawyer star even brought along a pic of Deacon with a new dog - and a fat lip!
Plus, Ava's musical tastes, Phillippe explained, aren't completely typical of tweens: Witherspoon's mini-me favors The Beatles and Al Green -- and she's not a Justin Bieber fan. (It's part of Phillippe's fatherly responsibilities to teach his kids about music, he said -- as long as the tunes are expletive-free.)
As for Knapp's baby-to-be, (the So Undercover star is in her second trimester) "Ryan doesn't know if he is the dad," an insider tells Us. "If he is, he will take full responsibility for the child."
