Katy Perry: I Needed Shrink After John Mayer Split

Most people would prefer the matter of their therapy sessions stay private, but most people aren't Katy Perry. In an interview with Harper's Bazaar, picked up by Hollywood Life, the 29-year-old singer says she only survived her breakup with John Mayer thanks to her "oracle" of a therapist. "What I've learned is that if you don't have the foundation of self-love first, you really have nowhere to pull love from to give it away," she tells the mag. "I want to mommy everyone. I want to take care of them. I want to save them, and I forget myself in the meantime. I learned that through therapy."

In case you weren't aware, John Mayer is one thing Perry has in common with her apparent "straight-up enemy" Taylor Swift—in fact, the bad blood between the singers started because of him, Page Six reports. Despite Swift's account that the feud with a certain unnamed female singer was business-related—TMZ reports that three dancers once left Swift, who apparently considered them "family," to return to Perry when she started touring again—a source tells Page Six that "Perry started making digs at Taylor" after Swift released the song "Dear John" about her breakup with Mayer following a brief affair in 2010. And so explains the Mean Girls reference. (More Katy Perry stories.)
