Katy Perry has resurfaced from her John-Mayer-Is-My-Boyfriend hiatus to attend the 2013 Grammys, rocking a true-to-form Katy Perry gown.

With jet black hair, the singer wore a mint green Gucci gown and we’re not sure, but it looks like Katy ignored those strict wardrobe-guidelines if her cleavage is any indication.

Katy was nominated for Best Pop Solo for her song “Wide Awake” but the award went to Adele as the first award of the night.
