Russell spills on Katy's sex life.

Russell Brand claims ex-wife Katy Perry used a wheelchair as a sex prop during their failed marriage.

Katy and Russell officially severed ties earlier this month as their divorce became final on July 16, 2012.

Russell filed for divorce at the very end of 2011, but it takes six months to become final in California.

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 license 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 honors at the star's fourth wedding.''
