Gary Barlow will never forgive Louis Walsh for not putting his act through on The X Factor.
There's never a dull minute during the live shows and this series is shaping up to be no exception.
Last week, Louis decided to put through Rylan Clark ahead of Gary's act Carolynne Poole, despite Carolynne giving the better performance on the night - prompting the Take That star to storm off the set.
And the bust-up wasn't just for the cameras - reports suggest Gary has sworn never to speak to the former Westlife manager again.
A source told The Mirror: "As far as Gary is concerned, Louis and his relationship is well and truly over. It may make TV gold on Saturday night but this feud is real. Unless Louis dramatically rethinks his approach, Gary won't have the time of day for him in this life or the next."
But perhaps Gary shouldn't be too surprised that Louis chose Rylan, after all, this is the man who brought us Jedward.
The producers of the show tried to patch things up between the pair earlier in the week by holding a dinner for the judges, but apparently the pair sat at opposite ends of the table and had only a few frosty words to say to each other.
Simon Cowell is said to be delighted at the drama and there are plans for the pair to be questioned about their disagreement at the start of the show, so expect plenty of fireworks.
