The pair, aged 17 and 19, hit out at the editing of the singing competition after they appeared to argue with Becky Hill over who got the best lines during the Battle Rounds.

Coach Jessie J later axed the singers, who insist they never fell out with Hill. They claim the BBC edited five days of footage into a few minutes to manufacture a row for ratings.
"I felt sick watching it. I had to leave the room because I couldn't watch it. They made their own story," Indie told The Sun. "They would take the answer and put it with a different question.
"There was one girl [on Twitter] who said we deserved to burn. People said we didn't deserve to be alive. We wouldn't have had so much hate if they hadn't edited us like that."
Indie's mum Charlie has since complained to the BBC and was recently invited for a meeting.
The BBC said: "There was a fair representation of all coaching sessions."
Former contestants J Marie Cooper, Emmy J Mac and Ben Kelly have also been critical of The Voice UK's editing.
