It’s been 20 years.

Musician Justin Timberlake took to his official IG handle on Wednesday to celebrate two decades of Celebrity, which includes many of their hit songs such as Girlfriend, Gone, and Pop. The album was released on July 24, 2001, and NYSNC—  one of the most iconic boy bands of all time— topped the charts.

In order to commemorate his band NSYNC’s final studio completing twenty years, JT posted a throwback video, in which he and his bandmates— Chris Kirkpatrick, JC Chasez, Joey Fatone, and Lance Bass are beatboxing their hit song Gone.

"20 years already?! What a time to be alive," Justin, 40, wrote along with the video.

The comment section was quickly brimming with love and nostalgic sentiments from JT’s fellow cohorts and fans. Joey, 44, wrote: "Yes we old !!", while Lance, 42, commented along the same lines but with a simple emoji of an old man.

JC Chasez and Chris haven’t added any comment of their own yet.

Other celebrities also channeled their inner fans and marked the day with NYSNC. Tom Brady wrote, “Young BOSS,” while rapped Juicy J left a comment that said, “Legends.” Erin Andrews also left a heartfelt comment, “One of the highlights of my life people.”
