Pete Wentz and his wife Ashlee Simpson-Wentz recently celebrated the birth of their first baby boy. For those wondering about the name of their baby boy, they don't need to look too hard. Just open The Jungle Book and you'll find half of it: Mowgli. The first half is slightly grittier and totally unrelated to any childhood reference: Bronx. Put the two together and you have it: Bronx Mowgli Wentz. Quite a mouthful from one of America's youngest celebrity couples.

Love it or hate it? It doesn't matter either way. Pete Wentz and his wife Ashlee Simpson-Wentz are quite proud of their choice. At a recent interview with Ryan Seacrest, Pete Wentz said, "We came up with Bronx. We've been throwing [ideas] back and forth for a while," he said. "It's kind of cool to leave the narrative as what it is. People are stoked, pissed or whatever. And you're like, you know what: I don't think anyone has the real story." Asked about their decision to use The Jungle Book as a reference, Pete Wentz said that The Jungle Book was significant to them as a couple. "The Jungle Book was something that me and Ashlee bonded over. It's a cool name," said Pete Wentz to Ryan Seacrest.

If you thought it wasn't for real, you're not alone. Even Ryan Seacrest had to ask whether the name Bronx Mowgli Wentz was a joke! However, Pete Wentz did confirm that it was totally legitimate. "No, no, no, Bronx Mowgli definitely is his real name, but I don't think that anybody knows what the real story is of why or how."

Asked about how he felt about Ashley giving birth to their first baby, Pete Wentz replied, "Pretty surreal. Obviously, some stuff my wife would freak if I said, but she's pretty much a saint. Right before she went into labor, I was like, 'Oh my God, I think I'm having a heart attack!' You've seen your wife in all this pain, and you really don't know what's happening. She took care of me and made sure I was OK and then we went into labor. That's why she's a saint." He continued gushing praises for his wife and added, "She's an amazing girl. She was like, 'I will make sure you're OK.' I didn't even stop to think, 'Well, you just had an epidural and you're about to have a baby!' Natural things start going on in your body. My heart started beating really fast."

Upon seeing their baby, both Pete Wentz and Ashley-Simpson Wentz said, "He's beautiful. He's perfect. We were instantly in love. It's impossible not to be!"
