N Sync have reunited for member JC Chasez‘s 40th birthday.
The five-piece had gathered to celebrate the occasion when Justin Timberlake posted a photo of them on Instagram.
“JC’s 40th… And, if you don’t know, now you know…” he captioned the snap, Digital Spy reports.
The last time the band performed on stage together was at the MTV Video Music Awards in 2013. However, that performance only lasted 90 seconds.
The rest of the group joined Timberlake at the ceremony to help out on very brief versions of ‘Girlfriend’ and ‘Bye Bye Bye’. Timberlake was given the Michael Jackson Video Vanguard Award after the performance.
N Sync formed in Orlando, Florida in 1995 before going on a “temporary hiatus” in 2002. In 2007, Lance Bass confirmed the band had broken up for good.
