CBS is out to make sure that no Janet Jackson nip-slip ever happens on the Grammy's this Sunday. Literally anything that can be seen as naughty - breasts, buttocks, and genitals - are all banned from the broadcast and a note was sent to all attending.

CBS Standards & Practices board issued a letter (which you can read below) that says any nudity, or what they consider nudity, is not allowed at the show on Sunday.

Subject: 55th GRAMMYS: Standard And Practice Wardrobe Advisory

-kindly confirm receipt of s&p standards-

***GRAMMYS 2013***

CBS Program Practices advises that all talent appearing on camera please adhere to Network policy concerning wardrobe.

Please be sure that buttocks and female breasts are adequately covered. Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack. Bare sides or under curvature of the breasts is also problematic. Please avoid sheer see-through clothing that could  possibly expose female breast nipples. Please be sure the genital region is adequately covered so that there is no visible “puffy” bare skin exposure. Please avoid commercial identification of actual brand name products on T-shirts. Foreign language on wardrobe will need to be cleared. OBSCENITY OR PARTIALLY SEEN OBSCENITY ON WARDROBE IS UNACCEPTABLE FOR BROADCAST. This as well, pertains to audience members that appear on camera. Finally, The Network requests that any organized cause visibly spelled out on talent’s wardrobe be avoided. This would include lapel pins or any other form of accessory.

Does anyone remember P!NK (pictured above) from 2010? That was just a bit racy by most standards but I guess things have changed so much in 3 years that it needs to be a completely "family friendly" show.

Place your bets now on who CBS will kick out of the Grammy's because they didn't follow the guidelines.
