Stepping out solo, Katy Perry hit the MET Ball at The Metropolitan Museum of Art in New York City. The "Hit n Cold" singer was all fancied up as she posed for pictures on the red carpet sans fiance Russell Brand.

Tweeting about the night's plans, Katy wrote, "On the way to the Met Ball, ready to light this party up... Sheeeot. This one's for the KITTENS."Meanwhile, Miss Perry is currently prepping for her upcoming nuptials with Brand - as the two plan to wed in Indian later this year.
