4 of Diamonds brought class to The X Factor 2016's six chair challenge tonight.
The four piece are a girl group made up of Caroline, Sophia, Yasmin and Lauren.
"We're modern but we put a kind of 60s urban twist on it," said the girls of their sound back during the auditions.
Wanting to impress Nicole Scherzinger in particular at their first try out the girls performed Meghan Trainor's No for the judges last weekend.
And Nicole was VERY impressed, as she commented: "I don't know how to say this... for me, you're my favourite girl group I've seen."
Nicole went on: "Everybody can hold their own, everybody has a different tone, a different style and can really sing."
But it wasn't Nicole they bad to win over tonight as the girls performed Jamelia's Stop in a bid to make Louis Walsh's six seats.
After the performance, Nicole was still in love: "There's something really cool and classy about you girls"
They also won over Simon Cowell and Sharon Osbourne, who just wanted a bit more sass.
However it was up to Louis if 4 of Diamonds got a seat, and could keep it...
The X Factor 2016 airs Saturday and Sunday nights on ITV.
