Happy birthday, JC Chasez! It's hard to believe that the former teen boy-bander turned 40 on Aug. 8. But, he and the rest and the *NSYNC crew look better than ever close to 15 years after putting the kibosh on their pop group.

Justin Timberlake, Joey Fatone, Chris Kirkpatrick and Lance Bass came back together to celebrate their pal's milestone birthday, and shared the cutest Instagram pic of their reunion.

"JC's 40th," JT captioned his photo on social media. "And, if you don't know now you know..."

The guys caught up at JC's small private party held at The Nice Guy in Los Angeles.

According to an insider at Us Weekly, the bash only included about 50 friends, one of whom was Justin's actress wife Jessica Biel.

We haven't seen all of the "Bye Bye Bye" singers in one room together since the 2013 MTV Video Music Awards, where they sang a medley of their old songs on stage during Justin's Video Vanguard Award acceptance performance.


The "Tearin' Up my Heart" boys decided to call it quits in 2002, after around five years together.

JT went on to find the most success as a solo star, both in music and film. In 2016 alone, the Grammy-winner put out the hit single "Can't Stop the Feeling," and will voice the lead role in the animated movie "Trolls."

There's no indication that *NSYNC is actually reuniting as a band, but this picture sure gave us a glimmer of hope.
