A remix of the song Singin' in the Rain by dance act Mint Royale is at number one in the UK singles chart.
The song stormed to the top of the charts after Britain's Got Talent winner George Sampson danced to it in the semi-final of the hit show.
It knocked R'n'B singer Rihanna's Take a Bow off the top spot and down to number two.
Meanwhile, Paul Weller's new album, 22 Dreams, went straight to number one in the album charts.
Last week's top selling album, Here I Stand by R'n'B star Usher, slipped down to number five.
Apart from Singin' in the Rain, no other new releases made the top 10 singles chart this week.
