Adele's wealth has risen by Â£14million in the last 12 months, making her the richest young musician in Britain.
The 23-year-old 'Someone Like You' hitmaker has risen to the top of the Sunday Times Rich List thanks to the huge success of her album '21', which sold in excess of 20million copies worldwide.
Steve Redmond, of the Entertainment Retailers Association, told The Sun newspaper: "Adele's been the success story of the past year by a mile. You only get an Adele once every ten years. It's success on a ginormous scale."
Cheryl Cole, Leona Lewis and Katie Melua are all in second place with an impressive Â£12million, while Adele's fellow Brit School alum Jessie J has made her debut appearance on the list for those aged 30 and under, with a fortune of Â£5million.
The rundown of Britain's highest-earning young actors is once again topped by 'Harry Potter' star Daniel Radcliffe, 22, and his Â£54million, up Â£6million from last year thanks to his latest film, 'The Woman In Black'. In second place is 'Twilight' star Robert Pattinson, 25, who has increased his wealth by Â£8million since last year, taking his total to Â£40million, while Keira Knightley, 27, still has an estimated Â£30million, the same as last year.
