Pete Wentz is trying to cut down using foul-language as his New Year's resolution, now that he has a newborn baby in the house.
The Fall Out Boy bassist and wife Ashlee Simpson had their first child together - Bronx Mowgli Wentz - on November 20, and Wentz is happy to play the new role of dad.
"I'm working on not swearing around Bronx," he told Extra in a new interview. "I know, I have a bit of a bad mouth."
Pete also told how he can't wait to watch his son grow and learn new things. "The thing I'm looking forward to is watching Bronx discover life... the first time he laughs, first time he crawls."
"It's kind of cool to go back to someone else and care for someone and have responsibility... It's one of the few aspects of life where the clichés are totally true."
Simpson recently labelled Wentz an "a**hole", after he discussed the pair's sex life live on radio.
