Los Angeles - Grammy performers have been told to cover up at Sunday's big music awards show, and keep their buttocks, nipples and genitals under wraps, reports Deadline.com.
In a "wardrobe advisory", the official US broadcaster of the Grammy Awards, CBS, also asked musicians and audience members likely to appear on camera at the 10 February Grammy Awards ceremony to avoid wearing brand names on T-shirts as well as clothing with political or activist slogans.
"Please be sure that buttocks and female breasts are adequately covered. Thong type costumes are problematic. Please avoid exposing bare flesh under curves of the buttocks and buttock crack," said the memo issued by CBS standards and practices department and obtained by entertainment industry website Deadline.com.
Janet Jackson's breast
"Obscenity or partially seen obscenity on wardrobe is unacceptable for broadcast," the note added.
The warning follows a lengthy court battle over indecency and obscenity standards on US network television.
CBS, a unit of CBS Corp, was fined $550 000 by the Federal Communications Commission for airing a glimpse of Janet Jackson's breast when her costume slipped while singing at the Super Bowl half-time show in 2004.
The fine was later thrown out and that decision was upheld by the US Supreme Court in June 2012. CBS has expressed "deep regret" for the incident.
Revealing clothing
The annual Grammy Awards ceremony honours the best musicians of the year, but is also a major promotional showcase for rising stars and upcoming albums.
In 2010, singer Pink performed upside down in a rose-coloured bodysuit, while Rihanna last year wore a plunging black dress on the red carpet.
Performers at Sunday's three-hour show in Los Angeles include Rihanna, Justin Timberlake, Maroon 5, Frank Ocean, Alicia Keys and Elton John.
*The 55 Annual Grammy Awards ceremony will aired live on Channel O (channel 320) at 03:00 on Monday 11 February and repeated at 19:30 on Vuzu (channel 116) later the evening.
