Their marriage may be over, but Pete Wentz and Ashlee Simpson's friendship is as strong as ever.

"Ashlee's been my best friend for five years. She's the mother of my child," Wentz said during Seacrest's KIIS-FM radio show Monday. "I have nothing but love and respect for her."

He's not exaggerating: the duo (parents to son Bronx, 2) were spotted making two separate fast food runs in L.A. over the weekend.

"Going through something like this isn't easy," Wentz added, "but we're friends and the most important thing is to put our son first."
