The event will take place at the iHeartRadio Theater in Los Angeles, and in addition to Katy's performance, she'll sit down with host Mario Lopez for a Q&A about the making of "Prism."

Katy will certainly have plenty to talk about tonight. "Prism" has already spawned a Hot 100 No. 1 hit in "Roar," and the first 300,000 U.S. copies of the deluxe version of the album includes #Prism seed paper -- Perry encourages fans to "plant the Prism and spread the light!"

Tonight's live event will also be recorded for broadcast on the CW Network on the evening of Friday, October 25.
