That's okay, though, because Twitter definitely noticed and made it known.
While the group performed their new single "What a Man Gotta Do," a close-up on the youngest Jo Bro revealed what appeared to be spinach stuck in his teeth.
Fans and haters alike had a field day with the accidental extra accessory.
See some of the hilarious reactions below.
Nick Jonas had food in his teeth during his performance and I think Joe and Kevin purposely didn't tell him as pay back for breaking up the band years ago— Allison (@AlliNichole7) January 27, 2020

I'm jealous of whatever is stuck in Nick Jonas's teeth— Kalie Shorr (@kalieshorr) January 27, 2020
For what it's worth, Jonas has responded and seems to be taking it all in stride. He joked that "at least you all know I eat my greens."
