TMZ Sports shared the exchange:
The pair played together with the Denver Broncos (2006-08) and the Chicago Bears (2012-14), and they were often dynamic together on the field. With Cutler under center, Marshall had four seasons with at least 100 receptions and 1,200 receiving yards. While things in Chicago didn't end well between the pair, their chemistry on the field was undeniable.
So was the genuine amusement Marshall displayed when seeing Cutler's now-infamous butt pic.
"Jay, what the hell you doing?" Marshall asks in the video, smiling. "Jay Cutler, I've known you since we got drafted in 2006. What the hell you doing?"
