X Factor winner Leona Lewis's single A Moment Like This has become one of the fastest sellers of 2006 and is set to go straight to number one.
One shop has been shifting more than 100 of her CDs a minute.
But some people are already asking if Leona will have a successful career or if she'll be a one-hit wonder?
The judges say with her incredible voice Leona's set to be a superstar but previous X Factor winners have been known to fade away fast.
Two years ago Steve Brookstein was crowned winner of X Factor. He sold 127,370 copies of his single Against All Odds and went straight to number one.
But he only stayed there a week and split from his record company soon after he won. He hasn't released anything since.
A year later Shayne Ward won the competition and again scored a number one with his debut single That's My Goal. His second single No Promises went to number two and his third went in at number 14. He's now working on an album for 2007.
In the meantime Leona's racing around the country doing loads of interviews and there is even talk of American record labels being interested in signing her up.
But only time will tell if this is the start of a massive music career for the girl from east London.
