According to The New York Post, Justin Timberlake may no longer be at William Rast by the end of the year. At this point, there are only speculations as to why JT could be leaving. Some say the drop in sales might be the reason for the split. 

Timberlake started William Rast with his friend, Trace Ayala, in 2005. The brand has since been an important part of the singer's style history. But with that said, maybe JT is just preoccupied with suits and ties right now.

William Rast has not denied Timberlake's departure, but that he's "eternally" connected to the label.
