JJ Watt unveiled a new look on Twitter that left fans in fits of laughter.

Watt changed up his hair for the Super Bowl, which drew lots of attention for his radical new style, so he changed things up again to end the month.

For the Super Bowl, he debuted a spiky look that looked like it would be popular decades ago.

Watt's Super Bowl look was compared to 90s boybands like NSYNC and the Backstreet Boys.

"J.J. Watt's hair looks like he got shocked touching a doorknob at Kevin McCallister's house," one fan said,

"J.J. Watt making some choices with that hair!" another fan said.

Watt saw all of the attention surrounding his hair and gave a hilarious response to it.

"You ever switch up your hair and wonder if anyone will notice? They notice," he joked.

On Wednesday, Watt decided to take his jokes a step further by implementing a radically different look.

This time, instead of going short and spiky, Watt sported long flowing locks with a thick mustache.
