Justin Timberlake and Ashton Kutcher are squaring off over which of them sparked the Trucker Hat Craze of 2003.

“It’s funny. I keep hearing Ashton Kutcher say how he was responsible for trucker caps. I’ve heard him make that statement before,” the SexyBack singer said in the September 2008 edition of Fashion Rocks Magazine.

J.T says it was actually he and childhood friend/William Rast designer Trace Ayala who spurned the once-popular fashion trend.

“Trace [Ayala] and I were wearing them when we were seventeen.”
