Ryan Phillippe & Alexis Knapp Expecting Baby?

Ryan Phillippe may be a dad again – his ex-girlfriend, Alexis Knapp, is pregnant and has told friends that the baby is his!

The baby is due in June, People reports, and Ryan “is aware of the situation [and] totally prepared to take responsibility should the child be his,” according to a source.

Ryan, 36, dated Alexis last summer and is currently dating Amanda Seyfried.

Ryan has two children, Ava and Deacon, from his marriage to Reese Witherspoon.
