Pete Wentz believes he's "great" at changing nappies.
The Fall Out Boy rocker has picked up a new skill since he welcomed his son Saint Lazslo into the world with his girlfriend Meagan Camper on August 20.
Speaking to PEOPLE.com, he said: "I'm a great diaper changer. There are a lot of things that go into it. Speed is a big part of it."
The 35-year-old hunk also has five-year-old son Bronx with his ex-wife Ashlee Simpson and insists he's prepared for what the future may hold as a father.
He explained: "I know the phases now, I know that they change and you are on the roller coaster and there are ups and downs and you're not falling off the ride."
Meanwhile, Pete admits little Bronx couldn't be less interested in his celebrity status and finds it funny when people are eager to have a picture with him.
He said: "[Bronx] comes to our [Fall Out Boy's] shows, but it's the equivalent to me going to my dad's job when I was a kid. At the end of the day, it's dad's job.
"All I am to him is his dad. When he sees people want to take a picture with me, he thinks it's hilarious."
