Katy Perry. Hear her roar.
Katy Perry. Hear her roar. (Jake Bailey)
Katy Perry just announced a tour that includes a stop in Denver on Sept. 30.

The 46-city world tour -- or, if you will, the sugar-coated sex circus -- will bring Perry to the Pepsi Center, along with Tegan and Sara. She'll be out in support of her latest record, Prism. (That's the one with "Roar" on it.)

Tickets will start at $29.50, though the on-sale date hasn't been announced yet.
