Cody is one of three acts on George's live team and will tonight she'll be performing for a spot in the semi-finals next weekend.
But George and Cody have both confessed that the song choice has caused a few issues.
While not giving away the track, Cody says it's not something she'd pick to sing but George "loves" the song and reckons Cody be "astounding" this evening.
George explained ahead of tonight's live show: "We had a little bit of a difference but what was great was that Cody was performing the particular song which she's going to do on Saturday and she was like, 'I'm not feeling it'.
"I was like, 'If that's you not feeling it, carry on, because it's f**king amazing'. What's great for me is that even when one of my artists isn't feeling it, she's still astounding."
In a chat with DigitalSpy, Cody admitted: "My song, I'm sort of doing it because George really loves the song."
She added: "It's not something that I would pick, but hopefully I can pull it off and it'll be amazing. I'm just going to try my hardest."
In tonight's live show each coach will have the power to save one act in their teams while the public will vote on the remaining eight contestants. The FOUR with the fewest votes will leave the competition.
