KATY PERRY says that RUSSELL BRAND announced that he was divorcing her in a TEXT MESSAGE.
In the July issue of "Vogue" magazine . . . Katy says, quote, "[Russell is] a very smart man, and I was in love with him when I married him. Let's just say I haven't heard from him since he texted me saying he was divorcing me on December 31st of 2011."
Katy met Russell at the MTV Video Music Awards in 2009. They got married in October of 2010 . . . but things went sour, quickly, 14 months later.
She says, quote, "At first, when I met him, he wanted an equal . . . and I think a lot of times strong men do want an equal, but then they get that equal and they're like, I can't handle the equal-ness.
"He didn't like the atmosphere of me being the boss on tour. So that was really hurtful, and it was very controlling, which was upsetting."
On top of that, Katy hints that there's also a MYSTERY REASON that Russell dumped her . . . and she knows what it is . . . but she isn't talking.
She says, quote, "I felt a lot of responsibility for it ending, but then I found out the REAL truth, which I can't necessarily disclose because I keep it locked in my safe for a rainy day.
"I let go and I was like, 'This isn't because of me, this is beyond me.' So I have moved on from that."
Even if Russell hadn't ended it, Katy was becoming irritated with him. (Which is surprising . . . mostly because it TOOK HER THAT LONG.)
She says, quote, "[He was] hysterical in some ways. Until he started making jokes about me and he didn't know I was in the audience, because I had come to surprise him at one of his shows. So. Hysterical to a point."
And he'd never show up at HER shows. She says, quote, "You saw that in [my movie, 'Katy Perry: Part of Me']. That wasn't edited to leave footage out. There wasn't any footage of him."
For the past year or so, Katy has been in an on-again, off-again relationship with JOHN MAYER. When she gave this interview, it was OFF-AGAIN . . . but she was spotted hanging out with him earlier this month.
She says, quote, "It's over. I was madly in love with him. I still am madly in love with him. All I can say about that relationship is that he's got a beautiful mind . . . Beautiful mind, tortured soul.
"I do have to figure out why I am attracted to these broken birds." (This issue of "Vogue" will be out next week.)
