Pete Wentz has revealed he talks to his unborn baby "all the time."

The Fall Out Boy rocker - who is expecting his first child with wife Ashlee Simpson - has been reading Armin Brott's birthing guide 'The Expectant Father' to get tips on how to support Ashlee, 23, throughout her pregnancy and how to bond with his child.

He said: "I talk to our baby all the time. '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."

Pete, 29, also hinted the baby won't be the last for the couple, who married in an intimate ceremony in front of close friends and family in May.

He added to People magazine: "This is the first one so we'll have to base the next one on how we do on the first one!"
