Katy Perry yesterday announced dates for her California Dreams tour this summer. The Xcel Energy Center will host her July 9th and Katy plans to get fans directly involved while on tour.

If you attend the show and check in at the X on Facebook you’ll receive special treats. You’ll also be able to submit your own photos of the show on Twitter, which will be worked into the live show and also be posted on Perry's website.

If you don’t go to the show, you can see Katy performing at this year's Grammy Awards in Los Angeles on February 13th. She's up for four awards, including Album of the Year.
