Pop superstar Robbie Williams has turned to voyeurism, and enjoys watching his London neighbours take drugs and walk around with no clothes on.

The ANGELS singer owns a 15th floor penthouse apartment overlooking the British capital's upmarket Chelsea Harbour and likes to spend his time monitoring the personal habits of the wealthy people who live around him.

Speaking from his balcony, Williams says, "See that apartment over there? A woman does coke there every night. And see that apartment there? A really fat old ugly bloke walks around naked and never draws his curtains.

"And down there, that's where this black woman - nothing wrong with that - naked - nothing wrong with that - came out dancing on her balcony. She started waving to me. Then she started singing and I thought, 'I'm b**gered if I'm waving back now.'

"I can't believe I left my night vision binoculars in LA."
