Gavin Rossdale chose Truly Ford to complete his team for the quarter finals, as Diamond, Carter and Keziah all got eliminated from the competition.
The results of the public voice saw Max Vickers and Sarah Morgan go through, but the Bush singer was left to make an incredibly tough call.
The three acts were speechless after the decision was revealed, while the coach admitted throughout the episode that was finding it difficult.
Diamond went first, impressing Gavin with her “flawless” and “pitch perfect” rendition of Wonder by Emili Sande and Naughty Boy.
Sir Tom Jones was also pleased, while will.i.am heaped praise on her and the “powerful” performance.
She was followed by 16-year-old Sarah Morgan, who delivered a haunting take on Whitney Houston’s iconic ballad I Will Always you.
The judges all praised her unique version, and Jennifer said: “It was so sweet. I just never heard a take like that on that song. I felt like you made it your own.”
Carter had been urged to tone down the volume on his performance, as Gav was shown giving him some tips for belting out Peter Gabriel’s hit Sledgehammer.
Will.i.am was full of praise and said he can’t wait to hear the singer performing his own hits because even his covers are delivered in a brilliantly believable way.
Student Truly Ford was up next as she tried to give a unique spin on Million Reasons by Lady Gaga, and it continued a successful night for Team Gavin as the judges were big fans of the performance.
Back to the boys next with Max Vickers, who was given a choice for the live rounds and went with I Bet That You Look Good On The Dancefloor by the Arctic Monkeys.
Will.i.am loved the energy, and his fellow judges couldn’t help but agree – with Sir Tom admitting even HE hadn’t been able to pull off the song that well.
Gavin chose Coldplay’s hit Trouble for Keziah Rodell, and once again the coaches were all delighted, and the Delilah legend said it was the best version of the track he’s ever heard.
Gavin admitted earlier in the show that he was facing a very tough decision.
“I’m more nervous than ever,” he told host Emma Willis.
The night also saw will.i.am take to the stage as he treated fans to a new track inspired by his time on the show.
However, viewers weren’t totally convinced, with one writing: “For the man who wrote Where Is The Love, Will.i.am makes some truly f***ing terrible music.”
