Four Of Diamonds made a triumphant return to The X Factor, closing the show with a performance that stunned viewers.
Louis Walsh's groups category had been looking a bit lacklustre as Bratavio were voted out last week and Brooks Way never actually made it to the live shows, but now his mentees have been bolstered by the return of the girl group.
His boyband 5 After Midnight also did well, but everyone was talking about the girls and their rendition of You Keep Me Hangin' On.
However, some felt they could have used the opportunity of coming back to choose a more catchy name.
And as ever with X Factor, people aren't keen when they find out the producers had a hand in forming a group.
Even so, we can't wait to see what they do next week if they survive the public vote.
And Little Mix are performing on Sunday night on the results show!
