Katy Perry hasn't spoken to her ex-husband Russell Brand since he texted her telling her he wanted to file for a divorce in late 2011.

The 30-year-old popstar and the 39-year-old comedian married in 2010, and had a cat together, named Rusty - a combination of their two names -but Katy revealed that she's changed the name of the cat, as well as cutting him out her life.

Katy said: "(Russell) hasn't spoken to me since he texted me saying he was filing for divorce. I don't want to talk about him -- my songs will say what I need to say.

"I still have the cat, but I've changed her name to Monkey."

Since splitting from Russell, Katy has been linked to both John Mayer and Diplo, and said that, even though the divorce caused her a lot of pain - and inspired most of her 'Prism' album - she's "excited" by her future love life.

When asked whether she'd closed herself off to love by the Daily Telegraph newspaper, the 'Roar' hitmaker said: "No, absolutely not. I'm excited by whatever it brings. I'm excited by my own evolution. I don't want to end up bittersweet. I have to evolve, I have to continue to push people's perceptions of me. As an artist I like to do that, keep people on the edge of their seats."
