"I had promised my mum I would do something with my life just before she died - that I'd do something with my singing. So I applied for Britain's Got Talent," The Sun quoted her as saying.
She added: "We'd seen a soloist singing on the TV just before she passed and I said, ''Is that what you want me to do, Mum? She said, 'Yes'. She had a good belief that I could do it. So I decided to do something about it.I couldn't straight away because the bereavement hit me hard."
Susan shot to fame earlier this year when she appeared as a contestant on the talent show, performing a jaw-dropping rendition of audition song "I Dreamed a Dream" from Les Miserables.
