Katy Perry: 'Part of Me' isn't about Russell Brand
"I wrote it two years ago, which is funny because everybody is like 'God, it sounds so current,'" she says. "Some people that I work with were like, 'You should just say you wrote it a couple of weeks ago.' I'm like, 'I'm not a d---, I'm going to tell the truth.' I wrote it two years ago when I was writing and recording Teenage Dream, [but] it didn't feel right on the record."
So despite lines like, "You can keep the diamond ring/It don't mean nothing anyway," it's not Brand the pop star was thinking of when she penned the lyrics.
"Sometimes I'm like, 'Am I living in 'The Truman Show'?' ... What's going on?'" she says. "It just feels like sometimes I'm caught in this movie where my life is paralleling my music! It seems very serendipitous, but, as un-fun as it sounds, I prepare everything. I'm overly prepared and kind of a control freak in the best of ways."
The couple, who married in late 2010 -- two months after "Teenage Dream" was released -- split in December 2011.
