Despite the fact online reports are circulating that Ryan Phillippe's ex-girlfriend Alexis Knapp is preggers with his third child, the actor looked perfectly gleeful when we spotted him in Hollywood yesterday afternoon...
Phillippe even waved hello and smiled to fans and photogs alike!
The 36-year-old is currently dating Amanda Seyfried. He already has two children with ex-wife Reese Witherspoon.
A source tells Us that Knapp "has been telling people he is the father." And another source adds that "Ryan doesn't know if he is the dad," but "if he is, he will take full responsibility for the child."
Knapp is indeed pregnant and she can next be seen in the Miley Cyrus movie, So Undercover.
