In scenes not shown in the main ITV programme, 17-year-old Abbey wowed the panel after telling cameras: "I'm in Girls Aloud tribute, I love being Cheryl."
Abby went on to reveal: "First I was Nicola, then I was Kimberley."
She added: "The judge I want to impress today is Cheryl."
Despite her working as Girls Aloud tribute however, Abby went on to sing Bounty by Christina Aguilera.
Simon reacted "Wow, you can sing!" in a what Cheryl seemed to take as a bit of a swipe.
Mel B however had some criticism: "It felt a bit too musical theatre to me, get rid of that drama stuff."
As for Cheryl's opinion, she had this to say: "That's the best rendition of that song we've heard.. but I don't actually like that song."
Louis added: "You look fantastic and you sing great!"
Despite the above, with four yeses Abby's through to arena auditions!
