Dear *NSYNC,

I want you back.

The whole band reunited Tuesday night for JC Chasez’s 40th birthday celebration. Justin Timberlake honored his boy band buddy with a special post on Instagram.

“JC‘s 40th… And, if you don’t know now you know…” he captioned the image.

*NSYNC is back together? JC is 40? What. Is. Happening.
