Grammy Awards 2013: Most Outrageous and Controversial Outfits [PHOTOS]

Every year, when the Grammy Awards roll around, eager viewers anticipate incredible performances and root for their favorite artists. But one of the biggest reasons to tune in to the award show is the red carpet - which is without a doubt the best part of the event.

In 2000, Jennifer Lopez arrived at the Grammy Awards dressed in a palm-print sheer silk chiffon Versace dress, which was definitely a head-turner. The following year, singer Toni Braxton came in a Richard Tyler white dress - exposing perhaps far too much of her body. Meanwhile, Beyoncé Knowles, who recently performed during the Super Bowl half-time show, stunned all in an ultra low-backed yellow dress for the 50th Annual Grammy Awards ceremony.

However, with the number of wardrobe malfunctions and nip-slips every year, CBS officials have issued a Wardrobe Advisory, asking performers and personalities to come covered up at the 2013 Grammy Awards.

"Please be sure that buttocks and female breasts are adequately covered," the statement read, "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."

The 55th Grammy Awards show will be held at the Staples Center in Los Angeles and will be aired on CBS at 8 pm EST(1am GMT) and be hosted by rapper and actor LL Cool J. There will also be performances by Justin Timberlake, Alicia Keys, Frank Ocean, Jack White, Maroon 5, Mumford & Sons and The Black Keys.
