Tonnes of fans have been flocking to buy the crooner's double A-side Evergreen/Anything Is Possible.
And almost 59 per cent of you have said you'll be buying it too in our very own vote.
The single's beaten the previous biggest seller, Band Aid's Do They Know It's Christmas? which sold 750,000 copies in December 1984.
By Friday afternoon, Will's track sold more than 800,000 copies.
And with a whole day of shopping to go, it looks like it's bound to be number one on Sunday.
Competition from Gareth?
It remains to be seen whether it will stay top when Gareth Gates' single, Unchained Melody, is released on 18 March.
And of course there's Rik Waller's effort, a version of the Dolly Parton/Whitney Houston hit I Will Always Love You which comes out on 4 March.
Make sure you check back for the new top 40 on Sunday!
