Rihanna angry over S&M video

Rihanna is angry that YouTube has labelled the video for 'S&M' 'inappropriate'

The video website deemed that only viewers over the age of 18 can view the clip, which sees the singer semi-naked and wearing a latex outfit.

On Twitter she vented: 'They watched 'Umbrella'...I was full nude.'

In retaliation she has posted the clip on her own site. She wrote: 'U can now view the S&M video on www.rihannanow.com UNFLAGGED!!!'

Meanwhile, Katy Perry teased the singer by Tweeting her: 'yo batch lemme borrow those latex dresses!' Rihanna responded with: 'ur a role model, u can't use those words!!', Perry replied with 'SUCK IT'.
