The coaches on The Voice UK formed a supergroup to launch the forthcoming BBC talent show, according to a report.
The Script's Danny O'Donoghue, Jessie J, Tom Jones and will.i.am teamed up to perform a version of the Black Eyed Peas hit single I Gotta Feeling, according to The Sun.
Their performance took place during auditions at the BBC Television Centre in London on Thursday, an onlooker told the newspaper.
The source said: "It was incredible to see such big names in music perform together. Hopefully this has set the bar for the rest of the show.
"Everyone was jumping out of their seats and dancing along. It was really exciting. The whole concept seems to be very different from The X Factor, which will be very refreshing."
The Voice UK is expected to air on BBC One in the Spring.
