*NSYNC and the Backstreet Boys are feuding again, thanks to Joey Fatone's big mouth.
Joey was a guest on HuffPost Live on Thursday, where he was asked why he thinks BSB are touring again after taking some time off.
"I feel like they just need the money," Fatone said. "No offense, guys. But I'm saying, if you think about it, it's like, 'Why are you coming back out again?'"
"If you come out with an album, great, do it up," he added. "I think it was kinda cool to see Kevin [Richardson] get back into it, but it's always interesting to see what and how you're going to evolve."
Well those words didn't sit too well with Nick Carter, who took time from his honeymoon to speak out earlier today on Twitter.
