The Margin was most upset to hear the tale from London of the mystery couple and the champagne bath. The couple - said to earn more than £20 million a year between them - splashed out £750 on three cases of Mumm to create the ultimate bubble bath.

But when they left their room to dine in the restaurant of the Portobello in west London, maid Helen Lena mistakenly emptied it.

Supermodel Kate Moss has angrily denied that she and boyfriend Johnny Depp were the celebrity couple left high and dry when the maid at the exclusive hotel pulled the plug.

Mr Johnny Ekperigin, managing partner of the hotel, said his superstar guests had laughed off the accident.
