Rihanna and Welsh soul singer Duffy were spotted as they were shopping for shoes at Barneys in New York City last week. I wonder how these two got to be friends. Maybe it’s the fact that in less than one month, the pair will help Fashion Rocks celebrates its fifth anniversary. I wonder if they are up for doing a duet. It’s going to be an interesting sound. The two singers will join other fellow performers at the September 5 celebration concert at New York’s Radio City Music Hall. Other performers include the likes of Chris Brown, Beyonce, Justin Timberlake, Mariah Carey and rapper Lil Wayne.
