Katy Perry Interview on Chelsea Lately

Katy Perry was interviewed at the awesome Chelsea Lately show, where she talked about her tour, her Grammy nomination and more. This was a great interview, so you must check it out. Also, Perry's single "Hot 'N Cold" has recently crossed over the three million digital sales, joining her single "I Kissed a Girl" in the three million group. Unbelievable, both her first singles combined have sold a total of over six million digital sales! That's crazy. Congrats to her.
