Reports emerged on Tuesday that his ex-girlfriend Alexis Knapp was pregnant with his child.
But actor Ryan Phillippe was pictured in LA yesterday with girlfriend Amanda Seyfried and the couple were all smiles for the cameras.
Alexis, an aspiring actress, dated the 36-year-old last summer but they split in October, the same month he began seeing Amanda.
And despite a brief split earlier this year, Amanda and Ryan seem to be back on track, the actress having confirmed the relationship in an interview with Elle magazine.
"Um, yeah. I've been 'seen' with him," she said.
Meanwhile, the Cruel Intentions actor is reportedly willing to take a paternity test to discover if he is the father of the child, which is due in June.
Ryan is already the father of seven-year-old Ava, and Deacon, 11, with ex-wife Reese Witherspoon.
