N'Sync Reunites for JC Chasez's 40th Birthday

— -- It's the reunion '90s kids have been waiting for.

In honor of JC Chasez's 40th birthday, beloved boy band N'Sync has finally reunited.

Justin Timberlake shared a snap of the momentous occasion on Instagram with the caption "Jc's 40th... And, if you don't know now you know..." The photo has already received 478,000 likes.

Lance Bass shared a picture of himself with the birthday boy, too.

The boy band split up in the early 2000s. In 2013, however, N'Sync took the stage for 90 seconds during Timberlake's MTV VMA performance.

Maybe for Timberlake's 40th, they'll grace us with a choreographed routine.
