The Mississippi rapper was a surprise number one last week when he toppled Pop Princess Kylie Minogue from the top spot.
Her catchy Can't Get You Out Of My Head is still the UK's second favourite single though.
DJ Otzi's Hey Baby (Uhh, Ahh) stays at number three whilst Five only make it to number four as the highest new entry with Closer To Me.
Meanwhile, Britney's still slaving away, but has fallen to number seven with I'm A Slave 4 U.
