Both Rihanna and Britney Spears are known for making super sexy videos -- but would they ever team up and shoot a video together? "I hope so," Rihanna said during an interview with New York's Z100 Monday morning. "I want to spank Britney." The "S&M" singer appeared on Elvis Duran's radio show to talk about the world premiere of a new remix of the song that features Spears. "It's very strange. Britney never does features. It was really amazing that she really wanted to be part of this song," Rihanna said. "She really liked the song to begin with, but it was a different story when she had to sing it, and she really wanted to be a part of it. It made it really, really special, because you never see two pop female artists doing songs together anymore." The collaboration, according to Rihanna, was an idea that came from the fans. "In order to do a remix, it had to be major," she said. "I asked my fans last week who they wanted me to collaborate with, and Britney was one of the most popular names." Though both Spears and Rihanna are likely to remain solo acts, Rihanna has a pretty good name picked out for if they wanted to form a girl group. "Just call us R&B," she said. Source: CNN
