Coaches from The Voice have recorded an all-star performance for the launch of BBC1's new series.
Sir Tom Jones, Jessie J, will.i.am and The Script's Danny O'Donoghue giave it their all as they performed together for the first time for the show's debut on Saturday.
The Voice is being launched on Saturday 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.
In the early stages of the contest the coaches assemble the singers they wish to mentor without actually seeing them - judging them solely on their voices.
A preview of the superstar line-up performing the track will be screened on The One Show tonight, which also features an appearance by Voice host Holly Willoughby.
