Tom Brady went "SICKO MODE" at Travis Scott's Coachella set ... grooving to the rapper's popular hits and flashing a Colgate smile for the camera.
The former NFL star hit up the second weekend of the popular SoCal festival ... and, an eagle-eyed fan captured him bouncing around to Scott's performance.
Check out the clip ... Brady's wearing a sweater, hood pulled over his cap -- and, he shoves his hands deep in his pockets, clearly fighting off the cold here.
