After the performance, Olly reacted: "Someone call a paramedic because I think Anne-Marie is having a heart attack right now! I don't know how you're going to make this decision."
Sir Tom added: "I think all three of you sang the hell out of that song."
Deciding the winner of the battle, Anne-Marie said: "You're both the best singers... I don't know what to do... I'm going to pick Wayne & Morgan."
But it wasn't the end of the road for Lauren as Will swooped in to steal her for his team.
Will said: "You have an amazing voice. Your skill is better than a lot of folks who are signed to labels."
Lauren reacted: "I'm so excited and can't wait to start this journey with you, Will."
