There's a new Phillippe in town.

According to his camp, Ryan Phillippe was planning to wait to take a DNA test to see whether he was the father of ex-girlfriend Alexis Knapp's unborn child, saying he would do the honors after the baby was born.

But apparently the actor being by Knapp's side when she gave birth was a sign, because she went ahead and named her daughter Kailani Merizalde Phillippe Knapp, according to a copy of her birth certificate that was obtained by E! News.

All questions aren't answered, however.

It certainly doesn't appear that Knapp is trying to cut her ex out of her life, but the space where the father is listed on the certificate was left blank.

If little Kailani is indeed biologically his, that makes three children for Phillippe, who also has daughter Ava and son Deacon with ex-wife Reese Witherspoon.

Knapp welcomed her baby on July 1 at Cedars-Sinai Medical Center in Los Angeles.
