Sideboob central!
CBS may have sent out a memo earlier this week laying down the law on what is considered acceptable for this year's Grammy Awards -- but some stars are already breaking the rules.
While the network said "bare sides or under curvatures of the breasts" are no-nos, Skylar Grey hit the red carpet moments ago in a sexy red dress that clearly went against the dress code.
She also showed off her huge back tattoo ... which isn't a problem, just a little tacky.
While she technically didn't break any rules, Katy Perry put the girls on display in a mint green gown she said was inspired by Priscilla Presley.
Ashanti went the underboob route in her sheer, flower-covered gown. Has she made any new music lately? Why is she there?
J.Lo made history with her very revealing green Versace gown back in 2000 -- so we knew she would be one to watch out for once the memo was sent out.
And she didn't disappoint, stepping out in this black dress that showed waaaaaay too much leg. Seriously, she's making Casper Smart look classy in this cheap outfit.
Kelly Rowland definitely upstaged Beyonce in this daring dress, which had some risque cutouts near her bikini zone and underboob area.
And we don't know who she is, but the girl Miguel had on his arm was definitely stealing the limelight from her famous man thanks to her "under curvatures."
Keep checking back, we'll update with more offenders as they hit the red carpet!
