Rihanna’s new video for single ‘S&M’ has been labelled as 'inappropriate' by YouTube.

The video sees Rihanna dress as a Playboy bunny and includes one scene where she is sporting a latex bondage outfit.

After previewing on YouTube last night, the site has now flagged the video as "inappropriate" for viewers under-18.

'S&M' is the forth single to be taken from Rihanna's chart-topping album 'Loud', which was originally released last year.

The singer responded to the news over Twitter: "They watched Umbrella... I was full nude."

Meanwhile, the singer has been caught up in a new naked photo scandal after a series of pictures allegedly emerged online.
