Getting into the holiday spirit, Katy Perry hit up the KIIS FM Jingle Ball 2010 in Los Angeles last night (December 5).
The ?Firework? songstress looked lovely on the Nokia Theatre LA Live red carpet in a lavender dress, before taking the stage for a high-energy performance.
Katy also dropped by the Trevor Live benefit event where she sang a song as part of the fundraising fun.
On Saturday (December 4), Katy supported her husband Russell Brand at Variety?s Power of Comedy night at Club Nokia. Brand was honored with an award at the shindig.
