A court has heard that Boy George was "obsessed with spanking" a male escort during a naked photo shoot.

First he had donned chains and leather straps as "decor" while Boy George (George O'Dowd) - photographed him as part of a drug-fueled erotic shoot he had arranged at his London apartment. Audun commented "He wanted to slap my arse. He was very obsessed."

Escort Audun Carlsen, 29, told the jury at London's Snaresbrook Crown Court that George had continuously wanted to strike his buttocks.

Audun who also alleges George beat him with a chain - revealed George forced him to put on a pair of handcuffs against his will.

He said "He asked me if I wanted to put on some handcuffs and I said, 'I don't want to have handcuffs on but I can take a chain around my wrists.' I didn't want to be tied up."

George and Auden originally met through gay website Gaydar, when the star booked the bisexual as a model in January last year. Auden travelled to 47-year-old George's home, where it is claimed George performed a sex act on him during the shoot. The men are also said to have used cocaine.

George has admitted handcuffing Auden but denies false imprisonment.

The trial continues.
