'N Sync's JC Chasez shows off full head of gray hair during his TikTok debut

JC Chasez made his TikTok debut with a full head of gray hair.

The 'N Sync singer posted a short video on the social media app wearing a pair of glasses, a tan jacket and a white shirt while he looks into the camera asking how this works.

"Am I doing this right?" Chasez captioned the clip, tagging fellow band members Chris Kirkpatrick, Lance Bass, Justin Timberlake and Joey Fatone.

Since its posting, Chasez's clip has received more than 1.2 million views and more than 107,000 likes -- with many people complimenting his shiny gray strands.

"Well hello there silver fox," said user Brittney Sotelo. Another fan chimed in saying, "JC went from teen heartthrob to silver fox and I'm here for it."

Another TikToker said, "This man has aged like fine wine." Chasez responded questioning, "red or white?"

While many onlookers were stunned by the singer's hair, it wasn't the first time he showed off slithers of gray.

Earlier this year, he was seen at several events, including Elton John AIDS Foundation's 30th Annual Academy Awards Viewing Party, sporting a head full of salt and pepper hair.
