Ben Affleck and Jennifer Garner
Their family is about to grow,
and now Jennifer Garner
and Ben Affleck
may be in the market for roomier digs.
"I guess they are looking for a bigger place now," pal Kevin Smith told PEOPLE at a the Maxim
magazine party on Saturday in San Diego where he attended Comic-Con.
The director-actor, who is a longtime friend of Affleck and starred with Garner in 2006's Catch and Release
, also revealed how he learned the news that the couple – who are parents to daughter Violet, 2 – are expecting again.
"I saw him last week. Ben came over to watch my movie (Zack and Miri Make a Porno
) at the house, and he told me, 'We're having another baby,'" recalls Smith.
He added that parenthood comes naturally to both stars. "[Jen] is such a Martha Stewart type. She is a perfect mom," he says. "And [Ben] is a great dad, which I found not that surprising, but it's a side of him that I never thought about before he became a dad. He's a great father. He loves that kid of his."
