Adele's album 21 has outsold Michael Jackson's Thriller to become the fifth biggest-selling album of all time in Britain.
Sales figures from the Official Charts Company show the follow-up to 19 has sold 4,274,300 copies, 500 more than the King of Pop's landmark record, which was released in 1982.
21 is continuing to sell an average of 20,000 copies a week.
Adele's album has spent 23 weeks at number one since its release last year.
It has already outsold such hit albums as Pink Floyd's The Dark Side Of The Moon and Dire Straits' Brothers In Arms.
The singer has also picked up six Grammys and two Brits.
Official Charts Company's managing director Martin Talbot described it as an incredible achievement for the north London singer.
To add to her many landmark records, Adele's achievement in overtaking Thriller in the all-time sales list is truly remarkable.
Thriller has long been recognised as one of the most iconic albums of all time - there is now no doubt that 21 can be spoken of in the same breath.
