People is reporting that Jen and Ben's new son joins his other sisters, 6-year-old Violet and 3-year-old Seraphina, in the Garner-Affleck brood. Jennifer announced she was pregnant back in August, and in January told Jay Leno that she and Ben knew the sex of the baby but they were keeping it secret.

Their thoughts on having a boy? "It would be so weird to have a boy," Jennifer told Ellen DeGeneres. But, she added, it would also be "cool and different." And Ben's thoughts? Well, according to Us Weekly, Jen told Jay Leno that she would have thought Ben would really want a boy, considering he was the only man in the house, but he told her, "Well, we have girls. We know how to do girls. My girls love me. I'm the big guy in the house." Well, get ready for a whole new experience, Ben, because you've got a son now!

The couple asked their daughters to help come up with names for their new brother -- and it seems the girls have Disney on the brain. Names they suggested include Donald Duck, Minnie Mouse, Peter Pan, Captain Hook, and Smee! What, no Ariel or Belle?

Do you have any guesses on what Jen and Ben actually will name their new son?
