The BACKSTREET BOYS and NSYNC are collabing! Sorta.

NICK CARTER and LANCE BASS broke the news on an Instagram Live that they’ve  been working on a special project in honor of Pride Month.

JOEY FATONE even joined in on the chat to tease his involvement, and they also said AJ MCLEAN might join in.

Nick said, “So basically, Lance, Joey, myself, A.J. maybe . . . we’re going to announce it in the next week … it’s going to be huge . . . we’re really excited.”

Nick and Lance teased the secret project back in September, and now it’s FINALLY happening.
