This evening the trio will be seen competing for a spot in the live shows after Jessie J pits them against one another.
But Indie and Pixie are concerned over the way the song has been split, saying they feel like Becky's backing singers.
Their coach Jessie tells the camera: "If there’s tension, I’m happy for that to be there, as long as it’s twisted into a good performance.”
Indie and Pixie took to Twitter today to insist that any clash between them and Becky had been blown out of proportion.
They wrote: "TO CLEAR THIS UP.. Regardless of whatever they say in news papers or on the voice tonight, us and @rebeckyhill get on swimmingly.....
"Us 3 got along so well it was silly. There was no tension, we didn't argue in any way.. We had a problem, sorted it and it was over. Xxx"
Becky added: "Just to clear this up everyone I LOVE INDIE&PIXIE VERY MUCH! we'll see what they say tonight x"
Tune into The Voice UK at 7:30PM to see their battle, which is quite amazing.
