Meagan Camper, Pete Wentz Bronx Mogwai
Meagan Camper, Pete Wentz Bronx Mogwai Father's Day came early for this Fall Out Boy!

Pete Wentz took his son Bronx and his girlfriend Meagan Camper to a celebratory brunch over the holiday weekend, and we can't believe how big the little tyke is getting! We also can't believe how curly his blonde locks are!

Fatherhood is clearly the rocker's favorite role! He admitted last year: "Having a child has definitely taught me patience on a whole new level, which is a really important lesson for me to have learned in life. I don't know what my threshold was before I realized that everything else isn't so important."

We wonder if Ashlee Simpson's little boy is adjusting to life as a cousin to Auntie Jessica's little girl Maxwell Johnson?!
