Ryan Phillippe's Ex-Girfriend Pregnant With His Child?Will Ryan Phillippe be adding to his brood of two? From the evidence, it looks that way. According to PEOPLE, Phillippe's ex-girlfriend, actress Alexis Knapp, is pregnant and in her second trimester.

The on-and-off couple dated for several months in 2010 before calling it quits in September of last year. According to sources close to Knapp, 26, who is 10 years Phillippe's junior, there is no question that the baby, due in June, is Phillippe's.

PEOPLE reports that although Phillippe isn't 100 percent positive that Knapp is carrying his child, if he is the father, he will be present in the child's life without a doubt.

"Ryan is aware of the situation [and] totally prepared to take responsibility should the child be his," says a source.
