The 25-year-old singer wore a backless Zac Posen dress, Casadei heels, earrings by Dijan from Lebanon, and a Judith Leiber Elephant bag.

Katy is nominated for Best Female Pop Vocal Performance for her hit single ‘Hot N Cold’. Katy‘s fiance Russell Brand was also present to show his support.

At a pre-Grammy gala event, Katy showed her respect for fellow pop star Lady Gaga.

“Really, I think that she just knew what she was doing, and she’s just playing the game on a totally different level,” Katy told MTV. “And people are now just playing catch-up with her. When I saw her on the AMAs, I was like, whatever. She was just in the Bowie/Prince kind of level.”
