Scottish singer Susan Boyle is convinced she will be worth 16 million pounds by next year.

After Boyle, 48, released her debut album ‘I Dreamed A Dream’, it became the biggest-selling CD of 2009 in the U.K., and has now sold more than 8.5 million copies globally.

The singer, who has reportedly been living off an allowance from Simon Cowell, will receive her first big payout from her worldwide sales when she turns 49 on April 1.

“I’m no April fool – I’m going to be worth 16 million pounds next year,” the Daily Star quoted her as saying.

And she is looking forward to buying a new five-bedroom, three-bathroom riverside property in her hometown of Blackburn, West Lothian, Scotland.

“Susan was teased from a child because of her birth date and told she would never amount to much in her life. She can still remember the taunts as if they were yesterday,” her brother, Gerry, said.

“But she rang me last week and was so happy. She said, ‘Gerry, if people look at me now they’ll realise I’m no idiot, no fool. I can buy whatever I want.’ I felt so happy for her.

“She’s had a lot of knocks in life and deserves everything good coming her way… The figures are staggering – eye popping.

“When Susan was told she dropped the phone and danced a jig around her front room, even though money is not her god and never will be,” he added.
