Russell Brand says that he and ex-wife Katy Perry practiced “wheelchair porn” during their marriage.

The comedian joked that the singer spent most of their time together in a chair used to aid people who have genuine trouble with walking.

He joked in a radio interview with Howard Stern: “She was very willing to do wheelchair porn. That woman spent 90 per cent of our marriage in a little electric wheelchair.”

Russell admitted that his sexual tastes have become tamer in recent years.

He said: “I don’t want porn anymore. There is no market for it in my life. I’ve got no kind of weird predilections especially.”

During the same interview, the Brand X host confirmed that he is dating Isabella Brewster.

Brand also described Perry’s single ‘Wide Awake’, which is thought to deal with the breakdown of his and Perry’s marriage, as a “nice song”.

The star recently applied for a licence to officiate at marriages in the United States.

Apparently he stumbled across a website offering the qualification during an afternoon surfing the internet.

A source said: “Russell is genuinely interested in the idea of marrying a couple.

“Now he’s getting matey with Tom Cruise, his pals have been joking that he could do the honours at the star’s fourth wedding.”
