American pop star Katy Perry opened up about former husband Russell Brand in Vogue magazine's July issue.

The 28-year-old Teenage Dream singer tied the knot with the comedian in October three years ago but divorced him after 14 months. In Perry's 3D documentary-concert Part of Me, she included details about the breakdown of her marriage and incidents related to the situation.

"[He was] a magical man" she said, "He's a very smart man, and I was in love with him when I married him. [He was] hysterical [funny] 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 he was hysterical to a point. I mean, I have to claim my own responsibility in things. I do admit that I was on the road a lot. Although I invited him time and time again, and I tried to come home as much as I possibly could. You saw that in the movie."

"Let's just say I haven't heard from him since he texted me saying he was divorcing me December 31, 2011," she added.

Perry, who was named Billboard magazine's Woman of the Year, also talked about her short-term romance with fellow musician John Mayer.

"Yes [I was seeing John, now it's] over," she said, "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."

Perry has also been linked with Twilight heartthrob couple Robert Pattinson and Kristen Stewart's split. According to Hollywood Life, Stewart told Perry "to back off" from Pattinson and is upset that they have been spending so much time together. However, she claimed she is not dating anyone right now.

"I'm not in a relationship, I'm just on my own - I am myself in my own bed. I have to be happy being alone, and I am happy," she said. "I believe that I will be loved again, in the right way. I know I'm worth it," she said.
