Grammy Awards stars asked to cover up

(CNN) — The very popular Grammy Awards is on Sunday and CBS officials are already asking the stars of the music industry to cover up before they head to the big show. A memo sent by the network's Standards and Practices Department asks talent appearing on camera to "adequately" cover their private parts, and avoid see-through clothing and "thong-type" costumes.

Stars are also asked to avoid T-shirts with brand name products, and any wardrobe item supporting an organized cause, including lapel pins.
