Perry embarks on a 50-city club and theatre tour starting at the Showbox at the Market in Seattle Jan. 23 and wrapping April 28 at Jannus Landing in St. Petersburg, Fla. Tickets go on sale Nov. 14-15.

The announcement comes as Perry’s second single, “Hot N Cold,” becomes a Top 10 radio entry in the U.S., Australia, Canada and the U.K. and is the most-listened to record on American Top 40, according to a statement. It comes on the heels of “I Kissed a Girl,” which held the No. 1 position in the States for seven weeks and was a No. 1 hit in 15 countries.

Alphabeat supports Perry on all North American dates and 3 OH 3! on the European dates. Choice venues include The Fillmore in San Francisco, The Wiltern in Los Angeles, House of Blues San Diego and the 9:30 Club in Washington, D.C.
