In Touch reports Phillippe was in attendance when Knapp (just shy of her 22nd birthday) gave birth to a girl at Los Angeles’ Cedars-Sinai Medical Center on July 1.
Phillippe is reportedly pursuing a paternity test to see if baby Kai is actually his daughter, but in the weeks prior to the birth, In Touch cites a friend of the actor who says, “He’s waiting for the DNA test to see of he’s the father, but he’s acting like he is.”
Knapp and Phillippe dated before splitting up in September 2010. Knapp’s pregnancy was later revealed in March 2011.
If he is the father, Kai would make baby #3 for Phillippe. He’s already a dad to Deacon (7) and Ava (11) with ex-wife Reese Witherspoon.
