Ex-NFL star Tiki Barber made his Broadway debut in "Kinky Boots" this weekend -- dancing and singing in a pair of red thigh-highs ... and he slaaaaayyyyyyed.
The former New York Giants running back played Don the foreman in the Broadway play which required him to flex his vocal range and hit a high note in one of the songs.
Look, he's no Celine Dion -- but he was pretty good ... and the crowd loved it. Dude even got his own bouquet of roses at the end of the performance.
