What's Katy Perry's Next Single? She Gives Us Some Clues

'I think it's a universal love song that everyone's going to be able to relate to,' Perry tells MTV News of 'Roar' follow-up.

Katy Perry may have been singing about finding her inner strength with [article id="1713155"]"Roar,"[/article] but with her second single off her [article id="1713176"]upcoming album, Prism,[/article] it's all about falling in love.

Before taking the stage at the [article id="1714419"]iHeartRadio Music Festival[/article] in Las Vegas this past weekend — where she performed the [article id="1714180"]track "Dark Horse"[/article] for the first time with Juicy J — Perry caught up with MTV News and told us about the follow-up to "Roar," which fans can expect sometime this fall.

"It's a love song and it's different from 'Roar' — it's not eighth-notey," Perry said. "And I think it's a universal love song that everyone's going to be able to relate to no matter the age, no matter male or female. It's my favorite song off the record."

Perry may have already given us a clue as to what song that could be. Earlier this month, when previewing tracks off her October 22 release, she told members of the New York media that her [article id="1713597"]favorite song off Prism[/article] was "Unconditionally," a slower-tempo love song. "There is no fear now ... I love you unconditionally," she sings.

Even though she will keep us guessing until the track is released, Perry did reveal that there will be many "shades of the '90s" on this album, not only with the music, but with her look as well. Perry traded in her jungle-theme attire at the iHeartRadio fest for a more grunge vibe, complete with two high buns, Converse sneakers and a plaid schoolgirl skirt.

"I got hair inspiration from pictures of Björk and Shirley Manson and wardrobe inspiration from 'The Craft,' " Perry said. "But I think my favorite pulls right now are 'The Craft,' Liv Tyler from 'Empire Records,' 'Clueless' — a little bit of stuff like that, or young Courtney Love when she's in Hole and stuff, like way back in the day, and a little bit of Spice Girls."
