Pete's in a band called Fall Out Boy, Ashlee Simpson is the failed-musician younger sister of a failed musician. They just had a kid named Bronx Mowgli, so Pete went on Howard Stern's radio mess to discuss matters important to all: boffing. Here's what he said!

Wentz said it took some time to convince Simpson to hook up with him. (He joked that he had to "beat her over the head with a club and drag her back to my cave.")

Once they did it, it was "the single best sexual encounter I have ever had," he said.

"It was at the Soho Grand Hotel [in New York City], and I'm looking in the mirrors, [thinking], 'Oh my God, you are [sleeping with] the girl of your dreams, and you can watch yourself!'" he said.

You're welcome!
