Pete Wentz: Ashlee Simpson had to comfort me while she gave birth!

Pete Wentz has said he felt like he was having a heart attack while wife Ashlee Simpson-Wentz was giving birth to their new son, Bronx.

The Fall Out Boy star was at Ashlee’s side throughout the delivery of Bronx Mowgli Wentz last Thursday evening.

Speaking to On Air with Ryan Seacrest yesterday, he explained the experience was “pretty surreal”: “Right before she went into labour, I was like, ‘Oh my God, I think I’m having a heart attack!’

“Natural things start going on in your body. My heart started beating really fast.

“You see your wife in all this pain, and you really don’t know what’s happening.

“[Ashlee] took care of me and made sure I was OK and then we went into labour. That’s why she’s a saint.

“She’s a 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!’”

He added that six day old Bronx is “beautiful, perfect” and the new parents were “instantly in love” with the boy: “It’s impossible not to be!”
