'X Factor' winner Leona Lewis is hopeful that she can sell enough copies of her debut single to secure this year's Christmas number one in the UK.
The 21-year-old singer beat 18-year-old rival Ray Quinn in the final of the show on Saturday night, becoming the first woman to win 'The X Factor'.
The CD version of her single 'A Moment Like This' is due to hit the shops on Wednesday, with one million advance orders of the single being recorded.
The single is already available for download, with 50,000 copies selling within 30 minutes of the track going on sale.
Speaking after her win, Leona said: "I'm just shocked. It's unbelievable. I feel like my dream has come true, the dream I've been dreaming since a little girl has come true."
"There were points I thought, 'You know what, I don't know if this is going to happen'," she said.
"But with the help from my friends and my family, they all kept telling me to believe in myself and keep on doing it and I did, and now I'm here and thank you so much to them."
Leona's mother said: "I'm the proudest mum in the world", with her father adding: "It's unbelievable, a dream come true."
Meanwhile, ITV announced it has agreed a new three-year deal with Simon Cowell, whose firm Syco produces the show and who is one of the show's judges, for more series of the reality show.
