Is Ryan Phillippe’s ex girlfriend secretly pregnant with his baby?

The aspiring actress, 26, is understood to have split from the 36-year-old Lincoln Lawyer star in October after around four months of dating.

Various U.S. media outlets are reporting the brunette is seven months pregnant with his child.

‘She has been telling people he is the father,’ a source is quoted as telling America’s Us Weekly magazine.

Ryan doesn’t know if he is the dad,’ according to a second source. ‘If he is, he will take full responsibility for the child.’

Knapp was sporting a noticeable baby bump as she left a Coffee Bean cafe in Los Angles with a female friend last week.

Not yet an established star, Knapp has only appeared in small roles in comedy movies Couple’s Retreat and Percy Jackson & The Lightning Thief.
