Perry has added a second show at the Staples Center in Los Angeles that will take place the night after her sold-out Nov. 22 show. The second show is “free” to thank fans for their incredible support throughout 2011. The Nov. 23 “Katy Perry Gives Thanks” show will wrap up the global superstar’s sold-out, 122-date California Dreams World Tour supporting Teenage Dream. The show will be filmed so fans are encouraged to recreate their favorite Katy Perry look as they may be featured on camera.

Today, Nov. 14, is the last day to request tickets on Katy’s Facebook page
