Sam sailed through last night's X Factor 2013 results, making it to tonight's grand final.
But speaking ahead of her last live performances, Sam revealed she had some reservations about auditioning for this year's series.
In a swipe at some of her rivals, she said: “I know so many people singing in pubs and clubs now who can p*ss over half the people who have been on this show – it really gets my back up.”
Sam explained how she had originally auditioned for the ITV show back in 2007, but didn't make it past the first unaired round of try outs.
"I didn’t have a lot of belief in the show many moons ago because, for me, the people I thought were relatively good never made it," Sam said. “I auditioned in 2007 when my dad had about a month to live.
“I didn’t mention it because I didn’t want it to be about my dad dying.
“I sang in a little room for about 30 seconds and got told to go home and come back next year. I never did it again because I had lost all belief in the programme.”
Speaking to the Daily Star Sunday, Sam suggested she'd have got further in 2007 had she had a sob story, such as talking about her dying father.
Sam told the tabloid: “I bet if I had mentioned back then that my dad was poorly I probably would have got through – I would have been in the final.
“I probably would have won it. That’s how I perceived it to be.
“This year they’ve taken the prison officer thing as my story.
“To be honest I wasn’t going to ever go back but I did this for me and I did it for my family, because my kids were enjoying watching it so much.”
The X Factor 2013 final continues tonight on ITV from 7:30PM, featuring performances from Gary Barlow, Elton John, Katy Perry and One Direction.
