Mom-to-be Ashlee Simpson lunches at Cafe Med in Sunset Plaza, Calif. on Monday.

Husband/rocker Pete Wentz has reportedly been reading The Expectant Father to learn how to support Ashlee through her pregnancy!

“I talk to our baby all the time,” he said. “The Expectant Father tells you that the woman, when she speaks, the baby hears her all the time. And the father’s voice isn’t familiar unless you talk to it, so I talk to it all the time.”

He also added, “This is the first one so we’ll have to base the next one on how we do on the first one!”

Looks like the musical pair will be trying for another one in the future!
