Ben Affleck 'desperate' for baby son

Ben Affleck is reportedly desperate for a son.

The actor and wife Jennifer Garner recently welcomed a second daughter but he is said to be eager for them to try for a baby boy.

"Ben's happy to keep going until he gets his boy," a source told OK! magazine.

"He has visions of dressing a little guy in Boston Red Sox gear, tossing a baseball around and cheering in the stands together."

The star has reportedly been trying to convince Garner that they should try for another baby.

"She's told friends that she's done," said the insider. "She jokes with Ben, 'If you want more babies, you'll have to find a way to produce them yourself!' but Jennifer is a big softie when it comes to giving Ben what he wants."
