Calling all starlets, make sure those buns and breasts are covered up at this year's Grammys.

CBS' Standards and Practices issued an advisory to all talent asking them to cover up for the awards show, which CBS will air this Sunday.

The memo, which was leaked to Deadline.com, asked that talent be sure their "buttocks and female breasts are adequately covered." "Thong type costumes" and "bare sides or under curvature of the breasts" are listed as "problematic." The memo also advises against "bare fleshy under curves of the buttocks and buttock crack" and sheer, see-through clothing. Genitals must also be covered "so that there is no visible 'puffy' bare skin exposure."

CBS also warns against brand names on clothing, obscenities and "lapel pins or any other form of accessory" that represents an organized cause.

CBS had "no comment" regarding the report.

The Grammys are known for star's over-the-top looks. Jennifer Lopez wore a now famous green Versace dress to the awards show in 2000 that left little to the imagination and last year Pink looked nearly naked as she performed wearing a flesh colored body suit.
