Ryan Phillippe was by his ex-girlfriend’s side when she gave birth to a baby girl on July 1. Actress Alexis Knapp welcomed an eight pound baby named Kai at Cedars-Sinai Medical Center and despite questions surrounding the paternity of the child, Phillippe was in the delivery room providing support to her. The two dated last summer before splitting up in October. Phillippe is believed to have taken Knapp to her doctor’s appointments throughout the pregnancy and he is allegedly waiting for a DNA test to see if he is the father of the baby. The actor has two children with his ex-wife Reese Witherspoon.
