Fall Out (Blonde) Boy! Rocker Pete Wentz lightened up his locks on Monday, Aug. 18, when he debuted his platinum blonde dyed hair on Instagram. 

“Prepared for new art on the horizon,” the Fall Out Boy frontman, 35, captioned the photo of his trimmed blonde tresses. 

Hair transformations aren’t the only changes in Wentz’s life these days. In February, Ashlee Simpson’s ex-husband announced that his girlfriend Meagan Camper is pregnant with the couple’s first child together.

This will be the second child for the “My Songs Know What You Did in the Dark” crooner, who shares son Bronx, 5, with Simpson. As he prepares to expand his family, Wentz’s ex-wife is putting the finishing touches on her wedding to fiancé Evan Ross.
