Rihanna's 'S&M' Video Restricted By YouTube, Banned In 11 Countries

'They watched Umbrella ... I was full nude,' Rihanna argues on Twitter; MTV chooses to air clip unedited.

[artist id="1940303"]Rihanna[/artist] has never shied away from being sexy in her videos, but it seems she's gone too far for some with her colorful video and lyrics for [article id="1657024"]"S&M."[/article] Not only has the video been deemed "inappropriate for some users" by YouTube, where viewers must verify they are 18 or older before watching it, but a handful of radio stations are also reacting to the song's racy lyrics.

In the video -- while singing lyrics like "Sex in the air/ I don't care/ I love the smell of it/ Sticks and stones may break my bones/ But chains and whips excite me" -- she dances around in latex, poking fun at the ball-gag-wearing media. The clip includes whips, a dog-leashed [article id="1657075"]Perez Hilton[/article] and Rihanna being handled by the press.

According to the U.K.'s Daily Mirror, 11 countries have already banned the video from airplay, and BBC 1 Radio won't play the track before 7 p.m. A rep for the radio station said they are considering airplay for the Loud track: "We are waiting for an edited version before deciding whether it will be played in the daytime."

As for rumors that MTV was looking to re-edit the clip, reps for the network told MTV News that the Melina Matsoukas-directed video was approved as is.

The singer herself is responding to the reaction and YouTube's decision to include a parental warning on the video, tweeting, "U can now view the S&M video on UNFLAGGED!!!" Also tweeting, "They watched Umbrella ... I was full nude."
