Tonight saw the second and final half of this year's knockout rounds as Will picked three artists for his team in the live finals.
Team Will was the last to perform as all eight of his contestants from the battle rounds took to the stage in turn, singing a song choice that they hoped would prove to their mentor that they should be in the live shows.
After the performances, Will's fellow coaches offered their thoughts as Boy George said: "I feel like I'm at a fantastic concert it's just such a pleasure to sit here and watch people sing and the audience reaction," going on to show support for Lyrickal.
Paloma Faith said: 'It's a fantastic team, if I were going to take three I'd personally take Eli, Theo and Faheem through."
And Ricky Wilson added: "If it was up to me, Lydia Lucy, Eli and then between Tom or Lyrickal."
But only Will.i.am had the power to pick the finalists for his team.
He began: "I hate this part of the show because some amazing singers are going to go home and only three go through and I deeply apologise for not being able to put everyone through."
Lauren Lapsley-Browne was the first through with Will saying: "My decision is based on this person has been fighting every step of the way and this person has improved, and this person is Lauren."
She reacted: "I'm not crying I'm just so happy!! I just couldn't believe every round I got through and now I've got to the lives, if Will believes in me, I have to believe in me!"
For his second choice, Will backed Lyrickal saying: "The decision they've made today and throughout the competition from the song they chose to the way they performed, they're ready to perform on the prime time big time."
Lyrickal teased: "I've got a few more surprises up my sleeve"
Finally through was Lydia Lucy, completing Will's team of Ls.
"Who amazed me, who I think should be out right now with records and videos and touring is the person I'm putting through and that is Lydia," Will remarked.
Lydia said: "I can't believe it, honestly, I'm overwhelmed, I'm so thankful, thank you Will."
But the news meant we said goodbye to five just as talented acts.
"It wasn't hard picking the three it was hard saying goodbye," Will said, as Charley Blue, Faheem, Tom Rickels, Theo Llewellyn and Eli Cripps all left the competition.
