Jess Glynne and Kylie Minogue are said to have turned down roles on The Voice UK 2017.
Jess and former coach Kylie have reportedly both said no to offers to join the series on ITV, along with Sir Paul McCartney.
Chatting to The Sun newspaper, Jess said she was 'just not interested' right now but didn't rule out joining the show in the future.
“There have been talks," the Take Me Home hitmaker explained. “People have approached me about it but it’s just not something I’m interested in right now to be honest.
“Maybe at some point in the future but not at the moment.”
According to the tabloid, Gary Barlow has also turned down a deal leaving show bosses still searching for a panel.
“Producers are having no luck finding respected musicians to join the show," an insider told the newspaper this week. “Jess knows exactly what it takes to be a star and ITV really want to make sure they find talent who will become fully-fledged artists."
The source added: “There is still time to find people for the show but the top choices for coaches have all ruled themselves out.”
The panel of the last BBC One series was made up of Boy George, Paloma Faith, Ricky Wilson and Will.i.am, but only Will is expected to stay put.
While The Voice won't air until 2017 on ITV, filming could begin as early as September this year and so the coaches will be confirmed within the coming months.
