Attention Grammy performers: The network wants you to cover your behind. Literally.

"Please be sure that buttocks and female breasts are adequately covered," reads a "wardrobe advisory" sent out from CBS' standards and practices department. "Thong type costumes are problematic." Aren't they always?

"Please avoid exposing bare fleshy under curves of the buttocks and buttock crack. Bare sides or under curvature of the breasts is also problematic." In other words, ladies, CBS would really rather not see your side-cleavage or under-cleavage... and that goes for rear-end cleavage, too, guys.

The memo, as leaked by Deadline Hollywood, does go on. "Please avoid sheer see-through clothing that could possibly expose female breast nipples," CBS tells the performers' reps. "Please be sure the genital region is adequately covered so that there is no visible 'puffy' bare skin exposure."

Memos like these have not been a matter of course prior to other Grammy telecasts. But Beyonce’s revealing Super Bowl wardrobe made some middle-American mothers and conservative pundits think they'd accidentally tuned in to the Lingerie Bowl, and it's hard not to wonder if all that Victoria's Secret-friendly costuming is what led the network to suddenly issue a very 20th-century-sounding call for (relative) modesty.

CBS is airing the Grammys just one week after the Bowl brought some heat down upon the network.

And it wasn't just the half-time entertainers riling up the right. The Parents Television Council urged the FCC to take action after MVP Joe Flacco dropped an F-bomb in front of 100-million-plus viewers right after the game.

The Grammys will be on a delay to allow for bleeping—something the Super Bowl may be subject to, someday, too, given the complaints—but the network isn't taking any chances with naughty words that would need to be visually blurred, either. "OBSCENITY OR PARTIALLY SEEN OBSCENITY ON WARDROBE IS UNACCEPTABLE FOR BROADCAST," reads the one part of the memo in all-caps. And don't try sneaking profanity through in Japanese or Latin, licentious superstars! "Foreign language on wardrobe will need to be cleared," the missive continues.

Or maybe the network isn't really worried about any performers in particular and, after the Beyonce backlash, just feels it has to cover its own behind by leaving behind a paper trail of prudishness.
