US rapper Lil' Wayne has returned to the top of the US Billboard album chart with 'Tha Carter III'.

The rapper's sixth album has exchanged places with Coldplay's 'Viva La Vida or Death and All His Friends', which falls to number two.

'Tha Carter III' sold 156,000 copies in the last seven days, according to statistics from Neilson Soundscan.

The album, which sold over a million copies in its first week last month, has now shifted more than 1.68million units in four weeks.

Elsewhere on the new chart, 'Camp Rock', a Disney soundtrack which features the Jonas Brothers, stayed at number three for the third week.
