Jay Z at Sundance premiere of Time: The Kalief Browder Story

Jay Z looked so gripped as he watched the premiere of Time: The Kalief Browder Story at the Sundance Film Festival in Utah on Wednesday.

The Show Me What You Got star applauded as he watched the forthcoming Spike TV documentary series. 

The 47-year-old, whose real name is Shawn Carter, was looking as trendy as ever in a green winter coat, pullover, jeans and grey beanie hat.

There was no sign of his wife Beyonce or their five-year-old daughter Blue Ivy but that didn't stop Jay from enjoying himself.

And no wonder for the self-confessed former drug dealer served as executive producer on the show, which features dramatic recreations as it tells Kalief Browder's story.
