We now know that Katy Perry's immensely anticipated third album will be titled "Prism" and is hitting shelves on Oct. 22, thanks to a giant golden truck that was rumbling through Los Angeles on Monday (July 29). And while few details are known about the actual music on the "Teenage Dream" follow-up, its first single may have a particularly ferocious title.
According to Idolator, Perry's forthcoming single will be titled "Roar." The track was reportedly written by Perry along with Lukasz "Dr. Luke" Gottwald, Max Martin and Bonnie McKee, who previously collaborated on Perry tracks like "Teenage Dream," "Last Friday Night (T.G.I.F.)" and "California Gurls." (Ed. note: this piece previously did not include Perry as a reported writer on "Roar," and has been updated).
