Pharrell is the UK's No. 1 single artist once again, as his song 'Happy' climbed to the top of the Official UK Singles Chart to reclaim the spot it held just over a week ago. The Despicable Me 2 soundtrack number replaced Pitbull & Ke$ha's 'Timber' at the top of the chart, after their song became the first UK No. 1 of 2014 last weekend.

This is now the second week 'Happy' has claimed the top spot, with 'Timber' falling one place to No. 2. Pharrell's single managed to shift 107,000 copies last week alone ('Timber' failed to break the 100k mark) meaning 'Happy' this week's top single by some way.

After appearing on the two most successful singles of 2013 - 'Blurred Lines' and 'Get Lucky' - Pharrell is already gearing himself up for a big 2014, and we're hoping that he is just as infectious as he was last year.

Filling up the spaces between the No. 2 and 6 spot was Avicii, Jason Derulo and FUSE ODG, with Avicii stalling at No. 3 for another week with 'Hey Brother.' Jason Derulo brought the 'Trumpets' to the No. 4 spot with his new single, whilst FUSE ODG's 'Million Pound Girl (Badder Than Bad)' finished off the top five.

The rest of the top ten was made up of Ellie Goulding at No. 6, Matrix & Futurebound/Marshall at No. 7, Eminem and Rihanna at No. 8, Martin Garrix at No. 9 and Beyonce featuring Jay-Z at No. 10. The full list is available at the Official Chart Company's website.
