Singer Susan Boyle's album is number one after it became the best-selling debut in UK chart history.
Boyle, a runner-up in ITV's Britain's Got Talent, has so far sold 410,000 copies of her album, I Dreamed a Dream.
Pop mogul Simon Cowell said he was proud of Boyle and added that the success could not have happened to a nicer person.
Boyle, 48, said the news was "fantastic". Her album is also expected to be a hit in the US.
Cowell said: "She did it her way and made a dream come true.
"In Britain's Got Talent she opened her mouth and the world fell in love with her, which is why her album has been the fastest selling of any woman making her debut."
Martin Talbot, of the Official Charts Company, described Boyle's achievement as "phenomenal".
Boyle's spokeswoman added that the singer was outselling Rihanna, Lady Gaga and 50 Cent in the US.
Mistakes made
She said Boyle was set to break Eminem's previous record for highest first week US sales in 2009.
Boyle, from West Lothian, struggled to handle the worldwide attention she gained after her first audition was watched by millions on television and the internet.
In June 2009, she was admitted to The Priory clinic after suffering an anxiety attack in the aftermath of the Britain's Got Talent final.
She also missed a number of live shows after suffering with exhaustion.
Cowell, who judges on Britain's Got Talent as well as being its creator, admitted that mistakes were made in handling Boyle speedy rise to global fame.
