You can't blame him. As much as 1D sings well, and obviously are super cute, but they don't dance like NSYNC. NSYNC's moves are just like no other!
Here's what JT said:
“I have not seen them on stage, but I’d be willing to say that we’re better than them. But I don’t feel like I’m laying down any gauntlet. … I’ve seen them a couple times and I like those guys. It’s interesting to see this whole wave of that come back around.”
