The competition was won by Mo Adeniran, with fellow finalist and countryman Jamie Miller, from Cardiff, finishing third on the night.
We reported earlier today that the final two contestants will perform one last song, and the victor will then go on to release the track at the end of tonight's show.
The victor of The Voice UK 2017 is Mo Adeniran.
As the victor, Mo will receive a recording contract with Polydor Records, home to artists such as Take That and Ellie Goulding.
The unknown man, who was dressed in plain clothes, could be seen running onto the stage in front of contestant James Miller, after it was announced he would not be the victor.
Despite this, he was in great spirits after his win, thanking his friends and family and dubbing his mentor Jennifer Hudson "the most incredible ever person".
Donald Trump places 'very high value' on talks with Chinese president
Tillerson replied that Trump looks forward to enhancing understanding with China and the opportunity for a visit in the future. It remained unclear whether Tillerson's apparently cordial Beijing visit would now pave the way.
And what about Gavin Rossdale, Will.i.am and Sir Tom Jones?
But the singer said all the hopefuls had "done amazing" in the series, which was airing on ITV for the first time since switching from the BBC.
The singing hopefuls and their coaches are to perform duets, although Rossdale will be left out of these as none of his acts have made it through to the end of the series.
Tom and Will.i.am are also said to be "in talks" to re-join the coaching panel. Whilst his version of "Unsteady" by X AMBASSADORS is now available to download and stream, it isn't officially his winner's single.
Instead, the victor will be bundled straight into the studio and will release a Winner's EP in the coming weeks.
