Alexis Knapp, Ryan Phillippe's pregnant ex girlfriend, has broken her silence.

Well, sort of.

A rep for the model-turned-actress, 21, cleared up some confusion to UsMagazine.com -- in particular, talk that Knapp expects a big payout from Phillippe, 36, the alleged father of her baby-to-be.

"She has never asked Ryan for any help, nor does she expect it," the rep tells Us. (As Us first reported, the Lincoln Lawyer actor does not yet know if he's the father of the child, but plans to take a paternity test.)

Don't expect any first-hand quotes from So Undercover star Knapp anytime soon, the rep added.

"Alexis has maintained her silence and will continue to do so...She continues to appreciate the love and support of her family and friends."

Meanwhile, an insider close to Knapp gave Us new details on her child, which is due in June.

"She does know the baby's gender, but isn't saying yet" the source says. "She's really excited to be a mom!"
