Girl group 4th Impact left The X Factor judges stunned during auditions this time last year.
Or rather 4th Power as they were known then.
The four piece from the Philippines flew half way around the world to sing in the competition, mainly lured by the prospect of seeing Simon Cowell.
Oh, and our Queen.
Made up of Mylene, Celina, Irene and Almira, 4th Impact are sisters and while they may have looked like the picture of sophisticated grace, they ended up bringing sass to the stage with a powerful performance of Bang Bang by Jessie J, Ariana Grande and Nicki Minaj.
There were dance moves, hair flicks and even rapping as 4th Impact rocked the stage to leave the X Factor judges overwhelmed with an audition that's since been watched 60 MILLION times.
Cheryl, who went on to mentor the group, told the girls after the performance: "You just absolutely took Wembley's roof off. You're so demure, the music kicks in and you all turned into little bad girls, it blew my mind."
"It's like your monsters! The passion, the voices, the attitude!" Rita Ora added.
"Wembley, what just happened?!" reacted Nick Grimshaw at the arena auditions. He added, correctly: "This is going to blow up all around the world."
Simon Cowell concluded: "People say it's the British X Factor, should it just be British talent but I've always said we welcome talent from around the world and you are incredible welcome."
4th Impact went on to finish fifth in the The X Factor last year and wow in the show's live tour earlier in 2016, which you can also relive in our video below...
