Mariah holds Leona off US No.1

Mariah Carey has fended off a strong challenge from Leona Lewis to remain at number one in America.

Her 'Touch My Body' enjoys a second week at the top of the Billboard Hot 100, with Lewis's 'Bleeding Love' - a former chart-topper itself - climbing from four to two.

Madonna's '4 Minutes' sticks at three, while rapper Lil Wayne climbs from seven to four with 'Lollipop'.

Elsewhere, Natasha Bedingfield vaults from 38 to 25 with 'Pocketful of Sunshine', while Radiohead score their biggest US hit since 1993, bowing at 37 with 'Nude'.
