Ryan Phillippe’s ex-girlfriend, Alexis Knapp, is pregnant – but she’s not pressuring the actor to be involved with her unborn child.
“She has never asked Ryan for any help, nor does she expect it,” a rep for Knapp tells PEOPLE.
According to a source, Knapp, who briefly dated Phillippe last summer, has told friends that she’s expecting the actor’s child in June.
Another source says that Phillippe, 36, is awaiting the results of a paternity test to determine if he’s indeed the baby’s father.
