British pop singer Robbie Williams is using a specially-made fat-melting contraption to help him lose weight.

The former boyband star, who has battled with his weight throughout his pop career, has had Vacunaut machines installed at his homes in London and Los Angeles.

It involves strapping on a 'wetsuit', corset and a suction hose and jogging on a treadmill.

ZEENAT SHAH, whose company make the Vacunaut, says, "I wouldn't say we're the only reason Robbie looks the way he does, but he follows the programme three times a week for 40 minutes."

CHRIS HEATH, the author of Williams' biography FEEL, adds, "Most days he appears in his suit, like an eccentric spaceman asking to be zipped up or unzipped."
