Despite some lyrics that make clear reference to a relationship falling apart and love gone wrong, Katy Perry insists "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,'" the pop star, 27, told MTV News about her latest single.
The song is full of jabs - "You can keep the diamond ring/It don't mean nothing anyway" etc. - leading many to conclude that it was a dig at Russell.
Not the case, says Perry, whose split with Brand remains amicable.
Katy and Russell wed in October 2010 and split in December 2011.
"Some people that I work with were like, 'Just say you wrote it a couple of weeks ago,'" she says. "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. It's not about [Russell Brand]."
Still, Perry admits that the timing is eerie in a sense.
"Sometimes I'm like, 'Am I living in The Truman Show?' 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."
