Katy Perry Sings 'Hey Jude,' Pays Tribute To Sir Paul McCartney, The MusiCares Person Of The Year (PHOTOS)

Katy Perry sure knows how to make an impression. The pop star, along with Coldplay, Tony Bennett, The Foo Fighters and Neil Young, honored Sir Paul McCartney Friday night as the MusiCares Person of the Year.

Perry gave a soulful performance of "Hey Jude," but it was the "Teenage Dream" singer's pink flower hat that grabbed everyone's attention.

The singer tweeted prior to the event that "Tonight's [look] is Petal Power themed."

During her last public performance at the offical pre-Super Bowl party, Perry -- sans petals -- flirted with Denver Broncos quarterback Tim Tebow by dedicating her provocative song "Peacock" to him. Perry recently split from her husband Russell Brand in December.

Check out more photos of Perry and her "petal power themed" hat -- and a video of her "Hey Jude" performance -- below.
