Rapper 50 Cent has accused Kanye West's record label Def Jam of doctoring sales figures in his battle with the hip-hop star.
Both stars released their respective third albums last week; a move which prompted 50 Cent - real name Curtis Jackson - to declare he would retire if the 'Stronger' star sold more albums than him.
Jackson insists bosses at West's record label have rigged the count of sales.
He says: "He's never had a fraction of the sales 50 Cent has. They could have one scan and have it count four times. West's entire career hasn't sold half what I sold on my first album."
