Singer Adele Adkins, a mother-of-one, has topped the young music rich list again, earning £5million in the last year, despite releasing no new music . It has been almost four years since her last album but that has not stopped Adele from earning £5million over the last year. Bringing her fortune to a total of £50million, the singer has retained her place at the top of the list of Britain’s richest musicians under the age of 30. The mother-of-one, 26, has double the wealth of her closest rivals – the four members of One Direction and their former compatriot Zayn Malik, 22 - who are worth £25million each. However, the country’s rising stars are hot on the singer’s heels. Ed Sheeran, 24, has enjoyed the year’s biggest rise, with a £13million boost taking his fortune to £20million and moving him from 23rd to seventh on the list. While Sam Smith, 22, is a new entry with £12million, placing him on par with Florence Welch, 28, and the pairing of Arctic Monkey’s guitarist Jamie Cook, 29, with his model wife Katie Downes, 30. Adele, full name is Adele Adkins, faces the toughest female competition from the Duchess of Cambridge’s wedding singer Ellie Goulding, 28, who, alongside Leona Lewis, 30, Jessie J, 27, and Katie Melua, 30, is worth £13million. Having also sung the theme song for the last James Bond instalment Skyfall, Adele’s hotly anticipated but much delayed third album is believed to be set for a release later this year. This is the fourth year in a row Adele has topped the list of the richest young musicians. With such impressive earning power, many of her contemporaries would look to channel their popularity into other lucrative activities. However, the singer has previously ruled that out, telling Vogue: ‘I have absolutely no intention of going into acting or making perfumes. Adele has amassed twice the wealth of her nearest competitors, the four remaining members of One Direction, plus recently departed Zayn Malik, who are worth £25million each . 'I am a singer. I will stick to what I am good at and not spread myself thin and become mediocre at everything I do.’ The figures have been compiled for the new edition of The Sunday Times Rich List, released this weekend and are based on the information about the stars’ land and property portfolios, stocks in public companies and known assets such as art. The young musicians still have a long way to go to catch their older counterparts. Sir Paul McCartney, 72, and his wife Nancy Shevell, 55, top the list of the richest musicians overall for another year. They have added £20million to their joint fortune this year, bringing their total wealth to £730million. Lord Andrew Lloyd Webber, 67, and the pop group U2 collectively round off the top three, with £650million and £431million respectively.
