Her boobs of course!

Speaking on E!s Daily 10, The Fall Out Boy star said "I would start with the breasts," when asked what his wife's best feature was.
But that's not all the new dad adores about his singer wife:
"Ashlee is the kind of person that understands me in a way that other human beings don't understand each other," he says. "I would say that we fit together kind of like Lego pieces, and that's how we're able to communicate."
Nice back peddling Pete!
He goes on:
"She's always there for me, she always has my back no matter what," Wentz says. "If I have to leave at 6 a.m. to go somewhere, she's packing my bag for me. I'm like, 'What are you doing up at 6 a.m.?' and she's packing my bag."
Aw. Young love.
