The 2013 Grammy Awards went down Sunday night in Los Angeles and toofab has all the photos from the red carpet!

This year, the Grammy organizers sent out a dress code to the attendees, prohibiting, among other things, "under curvature of the breasts" and "puffy bare skin exposure."

And some definitely didn't follow the rules.

Amber Rose showed off some curves, her 8+ months baby bump! She and boyfriend Wiz Khalifa are expecting a baby boy in three weeks. She glowed AND followed the dress code.

Jennifer Lopez kept covered up top, but not below the waist! "It said nothing about leg," J.Lo joked, referring to the rules. Somehow we think there will be a "no exposed thigh" clause next year.

It looks like Ashanti didn't get the memo, because she hit the carpet with her boobs peeking through her keyhole dress (which also featured a thigh-high split).

Others, like Kelly Osbourne and supermodel Karlie Kloss shirked the rule by wearing dresses with cutouts. Check out all the stars ... and even an astronaut ... by clicking the "Launch Gallery" above!
