At the Victoria’s Secret PINKapalooza back-to-school collection launch, it was a very pregnant Ashlee Simpson that stole the show.


There to support her new hubby Pete Wentz and his band Fall Out Boy, the flame haired singer rocked out backstage in a floor length dress as the band performed their classic hits together for the first time in months.

The newlyweds are expecting their first child together, and the expectant father was happy to gush to OK! about how he’s preparing for the big day.

"I’m reading all the books," Wentz said. "The best one I’ve read so far is "The Expectant Father." I’m talking to my dad a lot. I’m talking to Ashlee’s dad a lot. We hang out with other people who have kids. You see the world in a different way. It’s exciting."


So how are Pete’s friends treating the new dad-to-be?


"My friends are all really excited for me," he tells OK!. "Andy [Hurley] was the first to respond to anything. Like, I sent out the email for my wedding and Andy responded seven minutes later like ‘I’ll be there and these are the sizes of my clothes.’"
