Britney Spears is enjoying a hit single in the US with a song that hasn't even been released.
Do Somethin' this week entered the Billboard chart at No. 100 even though the track has not been officially released by the 23-year-old's record label Jive Records and is not being promoted by the company nor by Britney.
The track, which peaked at No 6 in the UK last month, made the chart based on airplay alone.
American radio stations began playing the track - one of two new songs included on last year's Greatest Hits: My Prerogative set - after being swamped by requests from fans.
