Adele is worth almost £15-million (R211-million).
The Someone Like You hitmaker reportedly makes £41 000 (R576 000) a day, according to accounts for the 24-year-old's company Melted Stone Ltd, which show she has £10.3-million (R145-million) in the bank and a further £4.6-million (R65-million) due in royalties.
Her huge fortune is down to the phenomenal success of her second album 21, which has sold 25 million copies worldwide, outselling her debut 19 three times over. The soulful singer's accounts were worth £341 000 last year before her music took off in America.
She recently splashed out £600 000 to buy her hardworking single mother Penny Adkins a plush new pad in Notting Hill, west London, as a thank you for working two jobs to support her daughter's ambitions to become a star.
Adele - who lives in a ten-bedroom mansion in Surrey with her fiancé Simon Konecki and her four-month-old son Angelo James - is currently renting Sir Paul McCartney's old Los Angeles mansion for £47 000 a month while she rehearses for the Oscars.
She is due to serenade the crowd with hit song Skyfall as part of the 50th anniversary James Bond celebrations on February 24 and is said to be extremely anxious about her performance.
A source told The Sun newspaper: "Adele is really nervous about her Oscars performance, so decided against staying in a hotel where there would be lots of people around.
"The property's up in the hills so guarantees her privacy. And what better place to get musical inspiration than an ex-Beatle's home."
