Without U hitmaker Usher will be teaming-up with troubled singer Chris Brown for his eighth studio album.

Speaking to Revolt TV, 35-year-old Usher said: ''The song that we did together, I think it answers a lot of questions. There's a lot mystery, I think, about a lot of things and the reality is we all are human. And though we may all experience hardship, it's in those times that people should really rally and remember why you fell in love with the artist, why you fell in love with the person.''

Usher further explained that he hasn't had the chance to talk to 25-year-old Brown since he was imprisoned.

He added: ''We have not been able to talk, but when he first came out of rehab, there was a lot of conversation back and forth and he was in a really good place, good positive place.''
