"I think that it's just such a great celebration of an amazing year in music, so many incredible artists and great performances tee'd up," he shared this past week. "I don't wanna give anything away, but I've got a few surprises up my sleeve, might be jumping up there myself... with two other guys who happen to be my brothers."
Nick sustained an injured this past week while filming something for NBC with his brothers, but didn't let that stop him from his hosting and performing duties on Sunday night.
"A fractured rib and some other bumps and bruises, but I am feeling really lucky," Nick said. "It probably could've been a little worse. So all is good."
