Pete Wentz Tells E! What an Amazing Wifey Ashlee Is

What's Pete Wentz's favorite feature on wife Ashlee Simpson-Wentz?

"I would start with the breasts," the new dad (son Bronx Mowgli was born three weeks ago) tells E!'s Daily 10.

But he doesn't just love Simpson-Wentz for her hot body.

"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."

Plus, she puts him first.

"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."
