J.LO & BEN BATTLE OVER HAVING BABY!

She’s pushing issue, but he feels too old

- 

DEMANDING diva Jennifer Lopez is doubling down on her demand to start a family with Ben Affleck — saying she’s waited long enough, according to pals who claim her henpecked hubby’s no longer on board with her baby dream and the marriage has hit a new roadblock!

“Baby Bennifer has always been a part of J.Lo’s plan,” notes a source. “At her age, people assume she’ll use a surrogate, but with the help of science she could still have a baby herself and that’s what she’d prefer.

“Either way, she’s got her heart set on it, so now that Ben’s changed his mind, it’s a big issue.”
