The weekend's X Factor double bill always has us talking, and as usual, it's not just the performances on our lips.
Dannii finds a new and brilliant way each weekend to display her ever-changing hairstyle, and this weekend was no different.
She ditched her classic quiff and went for vintage curls - a look that was very fitting with the Rat Pack theme of the performances.
Cheryl also went for the glam factor once again, giving us another fabulous updo.
We couldn't take our eyes off her sparkling headpiece; it was the perfect finish to her already dazzling outfit.
Rachel Adedeji may have waved goodbye to her quiff, but Dannii's returned on Sunday, looking better than ever.
We admire Dannii's ability to turn her quiff into a variety of different looks. She is able to pull off chic and effortless, rock star, and now Hollywood glam can be added to the list.
Cheryl's sleek, straight and shiny hair also returned, after a short absence.
She sported a side parting and half up-half down do, which was backcombed to give Cheryl that all-important volume.
There hasn't been a single show where the female judges haven't looked the picture of perfection.
And we don't think that day will come any time soon, either.
