Pete Wentz had been rocking his natural curls for quite a while, but yesterday the rocker decided to chop off his fro!

Wentz posted the pix of his new cut on his web site after spending the weekend enjoying fast food with soon-to-be-ex-wife Ashlee Simpson (where he hid his new 'do.)

This morning, Wentz called into Ryan Seacrest's show to proclaim his affection for Ash.

"Ashlee's been my best friend for five years. She's the mother of my child," Pete said, adding, "I have nothing but love and respect for her."

Wentz, who's currently working out a custody agreement with Simpson, went on to say "Going through something like this isn't easy, but we're friends and the most important thing is to put our son first."
