Pop superstar Katy Perry is to celebrate the end of her California Dreams tour in style by playing a free concert for her fans in Los Angeles.

The I Kissed A Girl hitmaker has hired out the Staples Center for a big celebration on 23 November - the eve of Thanksgiving holiday.

Announcing the news in a taped interview for the Ellen DeGeneres Show, which will air on Friday (11Nov11), Perry explains, "I am giving thanks to all of my fans. This is my big announcement on Ellen that no one has heard about or knows about.

"I played 121 shows... and I want to finish it off by renting out Staples (Center) myself and giving a free concert to anyone in the world that wants to come."
