'Hold It Against Me' hitmaker Britney appears on a remix of Rihanna's recent raunchy single 'S&M', with the Barbadian singer promising the results are "sexy".
She tweeted: "I got a #SEXY collabo comin your way supa dupa soon!!!! OH YEAH!!! By popular demand... Its BRITNEY BITCH!!!! (sic)"
Britney responded, tweeting back: "You're such a tease! I like it, like it. You think they're ready Ri Ri (sic)?"
Rihanna added further praise for the star, writing: "Britneyspears One of the biggest worldwide popstars! U gangsta #EPIC (sic)."
Britney returned the compliment, writing: "You ain't so bad yourself honey (sic)."
'S&M' caused controversy when it was released in January, with its raunchy video - which sees Rihanna simulating sex with a Blow Up doll - reportedly banned in 11 countries, mainly in South East Asia.
It was also edited for commercial radio in the UK, with certain words including "sex", "whips" and "chains" omitted.
A release date for the remix has yet to be given.
