The 49-year-old singer saw her debut album, I Dreamed A Dream, and her second album, The Gift, both go to number one and only two other groups have managed to do this as well - The Monkees and The Beatles.
Her new offering was recently released and has been named the fastest-selling holiday album in the UK and the US since records started.
Her debut album, I Dreamed A Dream, sold over 10million copies.
Speaking about the new record, Boyle said: 'I've never felt happier in all my life. This is an amazing result and one I never expected.'
Music boss and X Factor judge Simon Cowell added: 'I'm thrilled for Susan, she has once again defied the odds. She is my superwoman.'
