Security is set to be heightened on The Voice UK this weekend over fears of a backstage bustup.
However these tensions have nothing to do with the coaches or their artists.
This weekend will see Liam Gallagher's band Beady Eye performing on the show, while Robbie Williams will also be there to pre-record a performance for next weekend's final.
According to The Sun newspaper, producers are set to keep the "warring pair" on opposite studios of the studios in Pinewood, Bucks.
"Relations between Robbie and Liam do seem to have become less hostile but the bosses aren’t taking any chances," a source told the tabloid.
They explained: “They had hoped they wouldn’t be in the studio at the same time but as Robbie’s tour clashed with the final, his performance has to be pre-recorded. So we have given them separate Winnebagos on either side of the studio and called in extra security to be on hand in case the pair do kick off.”
Beady Eye will be seen performing along with Avril Lavigne on Saturday night's live semi-final, although like Robbie, Avril pre-recorded her performance earlier.
Robbie meanwhile be seen on the final on June 22, which will also see a performance from Michael Buble.
