Russell Brand claims divorce is a tough process because "there is a lot of admin".

The British comic actor filed legal papers to end his marriage to singer Katy Perry in December last year. The pair got married in India after a whirlwind romance but announced their split after just 14 months of marriage.

Russell has joked that the lengthy procedure to become a single man again is difficult, but he has turned to meditation and yoga to help him relax.

"I suppose divorce is difficult isn't it? Because of the admin. There is a lot of admin," he quipped during an interview for UK TV show Lorraine. "I am really in tune with some beautiful things. Firstly, I don't want to sound like a lunatic but if you meditate and do yoga you become attuned to different energy that is constant and very beautiful. Some people would call it God, some people would call it karma; I call it sexual charisma."

Russell insists he is coping well with the breakdown of his marriage. The 37-year-old Hollywood star has only good things to say about Katy and doesn't regret tying the knot.

"It did work out in a way, because you are married for some time and that is really good and then you are not married and that's really good," he explained. "You just have to have acceptance of things, you know? She is a person that I love but now this is a new time.

"We were for that amount of time, now this is a new time."

Even the persistent rain in London has failed to dampen Russell's spirits. The star was thrilled to be back in the UK to promote his new movie Rock of Ages, claiming he misses the changeable weather since moving to America.

"Don't worry about the rain," he smiled. "If you live in Los Angeles it's nice to come here and look at the grey, dingy, low hanging sky, the sparkling rain, glorious moisture. It's nice!"
