Pete Wentz: Ashlee Simpson craves green olives and pickles

What's mom-to-be Ashlee Simpson craving these days?

"Green olives and pickles!" her husband Pete Wentz revealed on Ryan Seacrest's KIIS-FM radio show Thursday. "Green olives on everything!"

He called her cravings an "anytime kind-of-thing. You always have to be ready."

He said the pregnancy is "really, really exciting.

"I heard women become mothers when they become pregnant, and boys become fathers when the baby is born," Wentz, 29, said. "So I don't feel all the physical things, but when I'm in the doctor's office, I freak out. It's ... crazy because it's this thing you made."

He said they still don't know the baby's sex, but is "hoping the doctor will see something in the next couple weeks."

The Fall Out Boy bassist — who confirmed Simpson's pregnancy in May shortly after they wed — says prepping for parenthood is "like making a record, but knowing you're going to mix it for the next 18 years of your life."

Expecting a kid has also affected "the way I'm writing. It's affected my perspective on the world. I care less about stupid things, petty feuds," Wentz said.

He also joked that he is turning into his dad.

"I get up at 7 ... complain," he said. "I come home [to] a pregnant wife and two puppies."

But Wentz (who admitted he made out with guys) doesn't mind.

He said his new goal is to "live in the suburbs and hang out with my kid."[source]
