Usher, 32, is nominated for three awards at the ceremony that will take place on November 21.
He told Extra: 'You guys are gonna love the show. I'm telling you, I've got an incredible treat for you.'
The rapper's two sons, Usher V, two, and Naviyd Ely, one, have been with him while he has recently been touring the world and he said he couldn't be happier.
He said: 'They have their own play area backstage. The ultimate inspiration and motivation is to know what I'm doing is for my kids. There are times in the show where it might get a little racy and they have to go in the back.'
