Lil Wayne is to become the first artist to sell a million albums in a week since 50 Cent.
In 2005, New York rapper Fiddy sold over one million copies with his second album, The Massacre.
Now Nielsen SoundScan, who monitor US album sales, report that New Orleans MC Wayne has hit the mark with his sixth album, Tha Carter III.
Although no other act in 2006 could sell more than 800,000 copies in a week, Kanye West came the closest last year.
Graduation, Kanye's third album, sold 957,000 copies last year, beating 50 Cent and his Curtis to the US No 1 album slot.
