Rihanna and Britney Spears have one thing in common – they are both not afraid to exploit their sexuality to sell records and now the duo is about to get frisky in a remix of Rihanna’s S&M. The Barbados-born singer asked her fans who they wanted her to collaborate with and an overwhelming majority chose Britney. Lucky for them, Spears obliged. The collaboration marks the first time Britney will be featured on another artist’s song. While talking about making the video for the remix, Rihanna admitted that she wants to spank Britney.
