Pop superstar Justin Bieber is celebrating after scoring his first British number one with the fastest-selling single in the U.K. to date.

The 21 year old's comeback track What Do You Mean? set a new streaming record on Spotify on Thursday (03Sep15), with 21 million streams in just five days, and now the hit has propelled Bieber to the top of the Official U.K. Top 40 Singles Chart with a huge 84,000 sales.

The track has gone to number one in a total of 90 countries, including New Zealand, Ireland and Sweden, and the singer expressed his gratitude to fans on Twitter on Friday (04Sep15), writing, "Thank you. Means a lot".

Meanwhile, last week's U.K. chart topper, Fight Song by Rachel Platten, slips to two, ahead of The Weeknd's Can't Feel My Face at three.

Bieber's fellow Canadian The Weeknd also flies high in the U.K. album countdown after debuting Beauty Behind the Madness in first place.

He dethrones Jess Glynne, who falls to two with I Cry When I Laugh, while Foals' What Went Down and Ella Eyre's Feline are new entries at three and four, respectively. Sam Smith's In The Lonely Hour rounds out the top five at five.
