Justin Timberlake commemorates 20 years of 'Celebrity': 'What a time to be alive'

The 10-time Grammy winner's post includes a behind-the-scenes video of Timberlake beatboxing and singing "Gone" with bandmates Lance Bass and Joey Fatone.

Bass left a grandpa emoji in the comments section, and Fatone noted, "Yes we old !!"

Tom Brady and Juicy J also commented "Young BOSS" and "Legends" respectively, while John Mayer—in typical John Mayer fashion—shared a more detailed sentiment: "We spun this record incessantly in the van on my first tour. Thanks for the memories."

*NSYNC consisted of Bass, Fatone, Timberlake, JC Chasez and Chris Kirkpatrick. The iconic boy band went on an "indefinite hiatus" in 2002, shortly after Celebrity reached No. 1 on the Billboard 200 (joining No Strings Attached), which was actually a definitely permanent hiatus.

Timberlake began his wildly successful solo career with Justified in November 2002. The 40-year-old has dropped five studio albums overall with his most recent offering, Man of the Woods, coming in February 2018.

If you are an *NSYNC fan suffering from denial and nostalgic, a pink limited edition Celebrity LP is available here to commemorate its 20th anniversary.
