So you've got fame, fortune and a new wife others covet? Where do you go on your honeymoon? If you're Pete Wentz, you head for the basement.

In a radio interview Tuesday morning (May 20) for "On Air With Ryan Seacrest," the Fall Out Boy bassist broke his silence about his [article id="1587667"]marriage this past weekend to Ashlee Simpson[/article], telling the "American Idol" host that the couple has decided to forego a traditional honeymoon for a more intimate, less expensive post-nuptials retreat -- in the basement of the couple's Los Angeles home.

"We got some blow-up palm trees," Wentz told Seacrest. "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. It's gonna look like we're on that private jet. We're gonna save that $30,000, you know?"

Wentz, who disclosed that the couple has a prenuptial agreement in place, also said he's not sure if the new Mrs. Wentz will take his name. "She legally is a Wentz. ... I don't know what she'll do with her stage name -- that's up to her," he said. "She hasn't decided that."

And how's married life treating Wentz? "I feel great," he said, before paraphrasing a line from the Kids in the Hall movie "Brain Candy." "It is sunny and 65 in my head."

According to Wentz, [article id="1587693"]last weekend's wedding[/article] wasn't a rushed affair, as has been reported. (Several magazines have speculated that the ceremony had to take place soon, before Simpson, who is reportedly pregnant, begins showing.) "It's been something we've been planning for a long time," the rocker said. "I gave her a promise ring four months ago."

Next, Seacrest asked the obvious question: Is the couple mulling baby names yet? Wentz didn't buckle, staying true to [article id="1585438"]the story[/article] he's been telling ever since the pregnancy rumors first surfaced.

"Ryan, this baby has not been confirmed," he insisted. "The only thing I'm confirming now is that we're in the basement on our honeymoon with these blow-up palm trees." He also evaded queries about his sister-in-law, Jessica Simpson, and her on-again, off-again beau 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."
