Pharrell's Happy Knocked From No 1 By Route 94
Pharrell Williams has been knocked off the number one spot in the singles chart by a 20-year-old DJ from London.
Route 94 said he was "over the moon" and planning a massive party after going to the top with his song My Love Ft Jess Glynne.
He told OfficialCharts.com: "I never thought 'I'm gonna write a massive Number 1' or a pop hit, or whatever, I just wrote it, and what happened just happened."
My Love features the voice of Jess Glynne, who also appears on the track Rather Be, a former singles chart-topper which is now at number three.
Katy Perry's Dark Horse holds firm at number four, while Brit Awards Critics' Choice winner Sam Smith is down three places to number five with Money On My Mind.
Williams missed out on an Oscar last week with his feel-good hit Happy, which is from the film Despicable Me 2.
It is his third UK million-selling single in less than 12 months.
The good news is that Williams is still rocking the record books and has scored his first UK number one album success with Girl.
It has become the fastest-selling artist album of 2014 so far, clocking up nearly 70,000 sales in the past seven days.
Its sales easily beat Bruce Springsteen's High Hopes, which sold more than 48,000 copies during its first week on sale in January.
Girl is a new entry at number one in the album chart ahead of Ellie Goulding, who climbed a place to number two with Halcyon, while Bastille's Bad Blood is at number three.
