Rihanna could cancel her performance of 'S&M' at this week's Brit Awads, it has been reported.

The singer who was due to perform a raunchy version of her new single 'S&M' at the Brit Awards tomorrow (February 15) is 'fuming' that she has been asked to tone down the sexual references in the song's lyrics, reports the Metro.

A source said: "She believes she won't do the song justice if she has to change the lyrics and it's a breach of her artistic integrity."

"She may scrap performing S&M altogether now and choose to do a safe pop number to keep the prudes at bay."

The video for 'S&M' has also been banned in several countries, while other broadcasters have vowed to only show it at more adult-friendly times of the day.
