But Susan Boyle may be the surprise winner of Britain’s Got Talent after she stunned Simon Cowell with her remarkable voice.
Unemployed and single, the 48-year-old has thick unkempt hair, bushy eyebrows and downy fuzz is noticeable across parts of her face.

She then stomped across the stage and began clumsily gyrating her hips towards the judges, prompting laughter from the audience.

‘I would love to be in musical theatre. I have just never had the opportunity,’ said Miss Boyle, who is from West Lothian in Scotland.
Moments later, the music mogul and fellow judges Amanda Holden and Piers Morgan were left speechless by her powerful rendition of I Dreamed A Dream from Les Miserables.
Miss Holden appeared close to tears as she sang, while Cowell looked almost adoring.
The audience gave the singer a standing ovation and cheered as she finished the song.
The turnaround was reminiscent of mobile phone salesman Paul Potts's success in the first series.
The judges admitted they had dismissed Potts because of the way he looked – namely, awkward and with wonky teeth.

They describe themselves as a modern version of the Von Trapps from The Sound Of Music.
They sang Michael Jackson’s I’ll Be There but the judges were damning about the parents' singing skills.
Show insiders have tipped teenager Elliot as the real talent of the band.
Other contestants include a witch, Fabia the erotic dancer, and a Greek Riverdance tribute act.

She joined the music mogul, Piers Morgan and Amanda Holden on the team but was sacked after little more than a week, amid claims that having four judges was ‘impractical’.
