Katy Perry talked about the superhuman inspiration behind ‘E.T.’, which appears on her new album ‘Teenage Dream’, in her latest YouTube video. “‘E.T.’ is kind of about meeting a boy who is definitely not from this world,” Perry explained. “Because he’s like a super lover and just has this power to him. It’s a fun song. I like taking a theme and just sticking to it.” The track is available on iTunes now in advance of the August 24th album release. Tune in to her Facebook page this Sunday at 9pm PST at to stream the album in full.
