Flo Rida makes it a month at US No.1

Rapper Flo Rida has extended his reign at the top of the US singles chart, notching up a fourth week at number one with 'Right Round'.

The track, which samples Dead Or Alive's 1984 hit 'You Spin Me Round (Like A Record)', is also top of the UK and Australian singles charts at the moment.

T.I. and Justin Timberlake remain at two in the US with 'Dead And Gone', while Lady GaGa holds steady at three with 'Poker Face'.

The highest new entry of the week comes from Miley Cyrus, who debuts at six with 'The Climb'.

Notable gains outside the top ten come from Kid Cudi, who climbs from 32 to 27 with 'Day 'N' Nite', and Beyoncé, who advances from 41 to 37 with 'Halo'.
