Ashlee Simpson and Pete Wentz’s little one, Bronx Mowgli Wentz, has provided much inspiration for his musical father. The Fall Out Boy bandmate claims that it’s because of his son that he wants to record an album of childrens music.

Wentz said that his band’s last album included a hidden track, a lullaby for his son. “We had so much fun doing it I’m going to put out an album of songs for children,” the musician admitted.

In addition to being his muse, Pete’s son has also helped his dad in dealing with his bipolar disorder. “With marriage and fatherhood, I’ve finally found two fixed points in my life,” Wentz has said. That’s good because Pete has a tendency to get stressed.
