Katy Perry, still with blue hair, wowed with her beautiful pink dress at the MusiCares Person of the Year Tribute to Sir Paul McCartney. The event took place on Fri., Feb. 11, at the Los Angeles Convention Center.

Many artists were in attendance including Alica Keys, Norah Jones, and Coldplay, who also gave performances. Other celebs like John Stamos, Tom Hanks, Yoko Ono, and Hugh Hefner joined 3,000 people in the audience. McCartney also graced the fans with a tune.

Perry herself gave a soulful homage to "Hey, Jude." She sung with a crystallized mic and a pink stand--not surprising for the pop princess. However, it was her red carpet look that really demanded attention.

The Friday night marked Perry's first public appearance since she officially filed for divorce with Russell Brand.
Katy's subsequent stunning appearance is a sign that a person is back in the "market," according to the Daily Mail.

She wore a pink, lace and silk gown designed by French designer, Alexis Mabille. She wore diamond earrings, bold lipstick, and a large hat... This enormous contraption was something like a blossoming flower. Hot or not?

"MusiCares is the Recording Academy's financial assistance program for members of the music community suffering from substance abuse issues and other critical illnesses," E! Online writes on their website.

Over $6.5 million was raised in yesterdays event.
