Pete Wentz Speaks on Ashlee Simpson, Marriage

Pete Wentz is speaking out for the first time since his weekend wedding to Ashlee Simpson. "We have signed a pre-nup," the newlywed rocker admitted on Ryan Seacrest's KIIS-FM radio show Tuesday.

As for whose assets are being protected, well, no elaboration.

As for Ashlee's name, "she legally is a Wentz ... I don't know what she'll do with her stage name, that's up to her. She hasn't decided that."

He said they're skipping out on a honeymoon (for now) and have been content hanging out in their basement in L.A.

"We got some blow-up palm trees," Wentz said. "A little fake-n-bake tanning booth... We're eating DiGiorno's pizza, getting in that tanning oven every once in a while, it's great. We're gonna save that 30 grand, you know?"

As for married life: "I feel great!" he said. "It is sunny and 65 in my head."

Pete Wentz still refused to confirm he got Ashlee Simpson pregnant.

When Seacrest asked why they decided to wed now, Wentz replied:

"I get the backdoor question you're asking, but it's been something we've been planning for a long time. I gave her a promise ring four months ago."

Seacrest later asked if he's thought about baby names. Pete Wentz laughed.

"Ryan, this baby has not been confirmed," he said.

"The only thing I'm confirming now is that we're in the basement on our honeymoon with these blow-up palm trees."

He was also mum on rumors about Jessica Simpson and Tony Romo.

"I don't know anything about what's going on with them," he said. "I'm so busy clearing up my own rumors!"

At the Alice In Wonderland-themed wedding, he said Jessica and Tony "seemed like they were dancing. It seemed like it was a good time."
