Katy Perry Videos: Katy Perry live perform her latest song Born This Way: On Katy Perry's current tour, which started last month in Europe, she's performed a number of cover songs in addition to her own material. Monday night in Paris, she continued the tradition by singing a unique, stripped-down version of Lady Gaga's "Born This Way," accompanied only by an acoustic guitar. It's not surprising that Gaga's song would appeal to Katy, since thematically, it's similar to her own hit, "Firework."
