After watching ex-husband Brad Pitt welcome three children into the world with lover Angelina Jolie, Jennifer Aniston is finally ready to open her heart to a baby bundle of her very own. And she already knows the perfect man to assume daddy duties, current boyfriend John Mayer.

“Jen feels so strongly that John is ‘the one,’” a friend of the 39-year-old actress spills to Star. “She knows he can handle being a dad.”

“She feels so loved,” the source explains. “John has really been doting on her. I mean, the presents, phone calls, romantic dinners — he’s laying it on thick. It all makes Jen feel really important and special.”
