Ashlee Simpson has had a furious bust-up with husband Pete Wentz — because he wants another baby, and she’s not so keen.

Simpson — who gave birth to the couple’s first child, son Bronx Mowgli Wentz, in November last year — believes a new pregnancy will interfere with her upcoming TV show.

“Pete wants Ashlee pregnant NOW,” a source told American tabloid the National Enquirer.

“He wants a big family. And he’s adamant that the children should be close in age.

“But Ashlee is consumed with making it as a serious actress. Each time Pete brings up the idea of a new baby, Ashlee groans, ‘We just had one!’

“While Ashlee does want more kids, she wants to wait a couple of years. It’s Pete who is getting antsy — and the baby issue is starting to create conflict.

“Ashlee worked hard to slim down and lose the baby weight after Bronx was born in November.

“She thinks another pregnancy now will slow her career momentum.

“And the last thing she wants is to jeopardize this new television gig because of morning sickness and dealing with the physical toll of a pregnancy.”

Ashlee’s new show, Melrose Place, debuts on the CW this fall.
