Coaches on BBC1's The Voice will show the contestants how it's done as they give an all-star performance to launch the series.
Sir Tom Jones, Jessie J, Will.i.am and The Script's Danny O'Donoghue will give it their all as they sing together for the first time for the series debut on Saturday.
The Voice is being launched on Saturday March 24 at 7pm, as ITV1 also starts its latest series of Britain's Got Talent, with both shows vying for ratings.
Stars of the new BBC show - reported to be earning more than a million pounds between them - had been tight-lipped about whether they would be joined in song on the programme.
But they will be seen performing Black Eyed Peas hit I Gotta Feeling for viewers as the first round of the show's "blind" auditions begin.
