The singer will be seen going head to head with [tag]Jaz Ellington[/tag] in this weekend's battle rounds.
It's understood that Will couldn't decide which of the pair to choose between, and so offered to sign one of them to his own label.
"Bosses were furious that he said in front of the audience he’d give Jay a deal," a supposed Voice insider said today. “The whole point of the show is to find a talent and give them a chance, not for the judges to profit from it by signing their own acts.
“Will thinks Jay has the attributes to be a star and doesn’t want to miss out on such a special talent.”
But a source close to Will told the Daily Mirror today that he loved 24-year-old Jay's voice.
The insider added: “He believes Jay has all the attributes to be a star and doesn’t want to miss out on such a special talent.”
The Voice UK continues tomorrow night on BBC One at 7PM and Sunday at 7:30PM.
