Actors, models and musicians dominate the Young Rich List of British millionaires aged 30 and under to be included in The Sunday Times Rich List 2012 published on Sunday, April 29. Sixty young millionaires will appear alongside the 1,000 richest people in Britain and the 250 wealthiest in Ireland in the definitive annual guide to wealth to be published in an extra 104-page magazine free with The Sunday Times. The richest young sportsmen will appear in The Sunday Times Sport Rich List 2012 published on May 6. Additional guides to wealth will appear at thesundaytimes.co.uk/richlist from April 29, with the Richest 2,000 people in Britain available from May 13.

Outside sport, more than half the wealthiest young people in Britain are entertainers. Actor Daniel Radcliffe, aged 22, who starred in eight Harry Potter films, heads the Young Entertainers Rich List with a £54m fortune. Radcliffe has increased his wealth by £6m in a year, helped by the success of his latest movie, the gothic thriller The Woman in Black. Twilight star Robert Pattinson has added £8m in a year to his fortune and is now worth £40m.

The young entertainer who has made the biggest gain in the last year is pop diva Adele, who has more than trebled her wealth after the phenomenal worldwide success of her second album 21. The 23-year-old songstress, from Tottenham, north London, is now worth £20m, an increase of £14m on her wealth in 2011, which puts her £8m ahead of the fortunes of Cheryl Cole, Leona Lewis and Katie Melua, who are in equal second place – each worth £12m, in the Young Music Millionaires Top 20 to be published in The Sunday Times Rich List 2012 on April 29.

The five newcomers in The Young Music Millionaires Top 20, each worth £5m, are all four members of JLS and Jessie J, 24, who has sold close to 1m copies of her album Who You Are and is a mentor on the BBC TV talent show The Voice UK. Jessie J, who has an endorsement deal with Pretty Polly tights, is one of a number of young actors and musicians who add to their wealth by modelling.

Rosie Huntington-Whiteley, worth £5m, is the latest model to join Britain’s Young Rich List. Now 25, Huntington-Whiteley, who grew up on a Devon farm, has been signed to the American lingerie brand Victoria’s Secret since 2006. Based in Los Angles she is branching out into films, with a part in Transformers: Dark of the Moon last year.
