Leona Lewis earned Ј1million for playing a private gig for the daughter of mobile phone billionaire John Caudwell over the weekend, according to reports.

The former X Factor winner played a seven song set for Libby Caudwell, who was celebrating her 21st birthday, and just 200 guests in Staffordshire.

Lewis was apparently joined by Caudwell for a rendition of her hit song 'Bleeding Love'. Boyzone star Stephen Gately is also said to have joined the singer on stage.

Lewis's set, which included 'Happy Birthday', was her longest public performance since winning the talent contest in 2006.

A spokesman told The Sun newspaper: "She did perform at a private event, but all details are confidential."

Lewis is due to release her second album in the autumn before heading out on her first full tour in 2010.

John Caudwell, one of Britain's richest businessmen, owns the mobile phone company Phones4U.
