Russell Brand has become obsessed with ‘air sex’

Russell Brand has reportedly become obsessed with 'air sex'.

The British comic has taken to the Japanese craze which sees fully clothed men simulating sex with an imaginary partner, often in an exaggerated way, and in competitions.

Russell, 33, has apparently been introduced to this practice by his yoga teacher friend Kazuko Burt, who told Britain's Daily Star newspaper: "Russell's been watching YouTube clips of air sex competitions, in which contestants perform the act to music, like air guitar for perverts. And he has been practicing with a variety of invisible partners to music by The Smiths.

"We told him about the World Air Sex Championships in Tokyo and he thought it was a delightful idea."

Russell is keen to get a first hand lesson in air sex from its Japanese creators.

He added: "Russell is desperate to meet the activity's creator, J-Taro Sugisaku and the reigning world champion, who goes by the name Cobra.

"And he's fascinated by the fact that J-Taro invented it because he couldn't get a girlfriend. This is all great material for his stand up shows."

Although Russell is enjoying his fake sex, the renowned womaniser has also been spotted with model and dancer Sydney Jackson, 22, in New York.

In September, a competition for the unusual erotic activity was held in Texas, US, drawing 1,200 spectators.
