London: Rapper Usher says he wants to perform a duet with Rihanna.
"Of course I`d do a track with her - hold on! We`ve been friends and our teams work together and we`ve talked about working together in the past, but it could potentially happen," contactmusic.com quoted him as saying.
"I would love to work with her - I think she`s an incredible artist," he added.
Usher even defended Rihanna`s latest video `S&M` which has proved to be controversial.
The singer wore a crystal-covered basque, fringed hotpants and fishnet stockings to perform a medley of her hits.
"Artistic direction is just that, you know, and obviously subjective. "Everyone has their opinion and it`s a family show. I think she is a responsible young lady and maybe the song represented the attitude of, you know, think about it like this- how long have guys been grabbing their crotches," he added.
