Grammys 2013: Katy Perry Ignores Dress Code And Flashes Cleavage In Revealing Dress (PICS)

Katy Perry clearly didn't get the memo about the 'no boobs' rule at this year's Grammy Awards.

The singer showed off her assets in a revealing green frock as she walked the red carpet outside the Staples Center in Los Angeles.

And here was us thinking it would be Katy's best friend Rihanna who would be first to flout the rule.

Katy turned up to see if she had walked away with the award for Best Pop Solo Performance for her song 'Wide Awake', but lost out to Adele.
