Katy Perry struck instant stardom with her hit, “I Kissed a Girl”, so who thought she’d end up waitressing at Denny’s?

Katy attended the first Warped Tour after party in Charlotte this week. There were over 500 kids that showed up to hang out with the Warped Tour artists! Several bands broke out impromptu jams in the parking lot, and Katy was inspired to take on waitressing duties. Lord knows why!

You can learn more about the after parties at www.dennysallnighter.com, there are four more scheduled in the next month and Katy will be at them all.

Check out this exclusive live video of Katy singing her hit song, “I Kissed a Girl” - in case you haven’t heard it yet today..heh.
