On Saturday, July 23, Katy Perry will perform at the Taco Bell Arena. If you are the parent of a 'tween, you probably already know this and have tickets for your kid and yourself--because you're not letting him/her see the sexy singer without a chaperone. Before you go, download the Katy Perry mobile app and learn everything you need to know about the sweetheart from Santa Barbara, Calif.
Open the app and you'll be greeted by Perry's alter ego, Kathy Beth Terry. A shy, nerdy eighth-grader who stars in Perry's video for "Last Friday Night (T.G.I.F.)."
From this screen, there are several ways to strengthen your knowledge of the California Gurl. You can stream 30-second previews of her songs, find upcoming shows, watch full-length music videos and look at photos.
You can check out "Katy's Korner," the one and only place for exclusive Perry content on the app. You can also drop by the oh-so-convenient online store and throw more of your hard-earned cash Perry's way. But having spent as much as you did on tickets for you and the kid to see her, you might need to skip that section.
