Hi Fred Durst, is that you?

The Limp Bizkit frontman, 50, surprised fans this week by posting a photo of himself with a very different look.

Known for sporting a baseball cap, and more recently, a full beard, Durst shared an almost unrecognizable selfie-style photo of himself with a full head of gray hair and a matching goatee beard -- with no hat.

Fans were seemingly stunned to see the rapper without his signature style and one Instagrammer even asked: "Are you okay my brother?"

Several others were quick to point out Durt's hair could be a wig.

While the "Rollin" rapper didn't answer any questions about his new look, he did post another photo of himself rocking the same look along with a pink shirt saying "dad vibes Chicago."

"You're literally glowing, this look is working for you," said one fan. Another shared similar thoughts by simply noting, "still hot."

Others have speculated that his latest hair transformation may have something to do with his upcoming performance at Chicago's Lollapalooza concert slated to occur July 29 - Aug. 1.
