Ryan Phillippe's pregnant ex-girlfriend doesn't "expect" his help.

Although it is not yet known whether the actor is the father of Alexis Knapp's baby, the model doesn't think he should take responsibility for the child.

A representative for the brunette said: "She has never asked Ryan for any help, nor does she expect it."

The actress, who is said to be due in June, dated Ryan briefly last year and reportedly told friends that the baby belongs to the 'Lincoln Lawyer' star.

A source said: "She has been telling people he is the father."

However, Alexis denies saying anything about Ryan and is refusing to publicly acknowledge the paternity of her child.

Talking to People.com her representative added: "Alexis has maintained her silence and will continue to do so. Any 'source' claiming to have been her or her camp up to this point is false."

"She continues to appreciate the love and support of her family and friends."

Ryan - who is believed to be dating actress Amanda Seyfried and already has two children Ava, 11, and seven-year-old Deacon, with his ex-wife Reese Witherspoon - will reportedly take a DNA test to determine whether he is to become a father for the third time.
