Will chose not to take Brooklyn through to the live shows after her performance of Let It Go.
In Saturday night's show, Will - who described Brooklyn as a “magical little creature” - said of the song choice: “Put it on freeze, stay cool! I’m happy she chose that, it shows me how daring and adventurous she is.
Speaking about spending time with Will, Brooklyn said: “It’s surreal to be working with Will, he’s so fun to be around. It does make me feel more at ease when I’m around him.”
When it came to the results, it was Lucy O'Bryne, Sheena McHugh and Vikesh Champaneri who made through to the live shows.
But Will quickly took to Twitter where he messages Essex teenager Brooklyn: "@artistbrooklyn let's work on music in the near future and make people "boooooogey"
Will also sent support to Newtion Matthews after he too missed out on the live shows.
"Thank you...your amazing" Will wrote to Newtion, who said of this time on The Voice: "It really has been an amazing experience! Thank u @BBCTheVoiceUK &everyone who showed love :)”
