Both singers tweet about forthcoming release

Rihanna and Britney Spears have revealed they are set to release a new collaboration song.

Both singers wrote about the forthcoming project on Twitter.

Rihanna announced it first, writing at Twitter.com/rihanna: “I got a sexy collaboration coming your way super-dupa soon! By popular demand… it’s Britney bitch!”

Spears then tweeted from Twitter.com/britneyspears: “Rihanna you’re such a tease! I like it, like it…”

Although the details haven’t been confirmed by either act’s reps yet, it is thought that the collaboration is likely to be a remix of Rihanna‘s ‘S&M’ single, after she tweeted last week asking fans whether they would like to see her rework it with another pop star.
