The I Dreamed A Dream singer has signed up for a one-off ITV1 special ahead of the release of her new album Someone To Watch Over Me, says the Daily Record.
"Despite the fact she's had this enormous success in record sales, she wanted to show her fans she's still the same Susan," a source told the newspaper.
"She still lives in the same house and has a normal life. Since the beginning of 2011, she has been filmed for a fly-on-the-wall documentary about her life."
Someone To Watch Over Me, the 50-year-old's recently-announced third LP, is released in the UK on November 7.
Boyle had previously said that she hoped to collaborate with Lady GaGa and Rihanna on the album.
