Jennifer Aniston allegedly got a huge birthday present from her beau Vince Vaughn. According to a published report, Vaughn said that he wanted to be the father of her children.

Life & Style magazine reports that Vaughn, 35, made the offer with no strings attached.

Vaughn allegedly told Aniston, ‘I’m not asking to be your husband.’

“You’re my best friend,” the 35 year-old funny man told Aniston at her 37th birthday party reveals a friend of the actress.

Vaughn also reportedly said, “I know how badly you want kids, so let’s have them together. We don’t have to promise each other anything, but we’ll always be the mom and dad.”

Aniston reportedly told her friend, “I didn’t know what to say. I love Vince, but I’m not in love. I want a child more than anything - but with my best friend? I don’t know what to do.”

Friends say that while Jennifer desperately wants kids, she’s not ready to jump into motherhood with Vaughn. “She’s worried,” adds an Aniston’s friend, “that at some future time she’ll feel she’s sold out.”
