Washington, Nov 10 Fall Out Boy member Pete Wentz has revealed that after his son Bronx Mowgli was born last November he was unable to write a song for six months.

Wentz, 30, who is married to Ashlee Simpson-Wentz, was amazed by how much parenthood affected his song writing, as he is now less selfish.

"For the first six months after Bronx was born, I couldn't write at all, and then all of a sudden I started writing again. I think it made me look at the world in a different way," Contactmusic quoted him as telling MusicRadar.

"We have a very selfish culture, and we all embrace it, and that's what 'I Don't Care' was supposed to be about, and what 'America's Sweethearts' was supposed to be about.

"I hate explaining lyrics because it feels like 'Whatever' but 'I Don't Care' was about looking at a picture of yourself in the mirror, like the ultimate form of narcissism," he added. (ANI)
