Rihanna 'surprised' to land Britney feature

Rihanna was prepared for rejection when she submitted a request to collaborate with Britney Spears, because the pop superstar "never does features".

The R&B beauty admits she was stunned to hear back from Spears, who expressed her excitement at recording a remix to the Umbrella hitmaker's latest single S&M.

Premiering the track on New York radio station Z100 on Monday (11Apr11), Rihanna says, "It's very strange. Britney never does features. It was really amazing that she really wanted to be part of this song.

"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 Bajan star reveals the idea for the duet came from her fans: "In order to do a remix, it had to be major. I asked my fans last week who they wanted me to collaborate with, and Britney was one of the most popular names."

And Rihanna hopes she and her new pop pal will get the chance to film a saucy new promo to accompany the reworked song.

The cheeky singer adds, "I want to spank Britney."
