THE Voice Kids UK viewers wanted the judges to leave the singing to the children after an impromptu performance.
Danny Jones, Pixie Lott, Will.i.am and Melanie C decided to do an improvised Christmas song during the debut episode of the 2021 series.
The McFly star lead the impromptu show with his guitar as they made up lines to sing.
Danny improvised some verses and then threw to Will.i.am to add some of his own words, while Sporty Spice and Pixie were relegated to over-qualified backup singers.
While the virtual audience was dancing along to the shorty ditty, viewers at home were less keen on the Christmas track.
"All the judges try it out sing each other in the joint singalong by throwing in random Woahs All over the place," wrote one disgruntled fan on Twitter.
Another added: "These judges just churn out any old crap and the audience lap it up!"
Tonight's premiere episode saw Mel C join the returning judges to decide which up and coming star they wanted to mentor.
