Alexis Knapp gave birth to an 8lb baby girl on Friday with ex Ryan Phillippe by her side.
Due to give birth the week before, the doctors at Los Angeles hospital, Cedars-Sinai, went ahead and induced labor on June 30.
When little Kai finally entered the world on July 1, Ryan and Alexis shared in happiness and congratulations.
How sweet! Sounds to us like he'll be there for Kai positive test results or not.
We applaud you, Ryan Phillippe! Way to go, hunk.
