They said they were after someone who would really blow them away this year, and it looks as though 11-year-old Asanda Jezile has done just that.
But it was her dance moves that really made her stand out from the crowd.
11-year-old Asanda Jezile impressed the judges with her performance of Diamonds by Rihanna
The mini diva even admitted that she would teach the Queen to be a diva should she win the show and perform on the Royal Variety Show.
Reaching every high note in the song, Alicia and Simon couldn't believe their ears.
David called her 'phenomenal' as Alicia and Amanda agreed.

But it wasn't all fun and games for the judges. First auditionee Steven Jackson, a 52-year-old part-time artist from Kent, failed to impress the judges with his impressionist act.
David said: “It was uncanny how unlike all those people you were.”
Sam Faiers and Imogen Thomas loved Asenda Jizele's performance
But animal lover Simon soon got his thrill for the night, as Diamond and The Ruff's dog - who they bought along for moral support - came onto the stage for a cuddle.
As the average singers stripped off on stage to a flurry of red buzzers, Simon sat and played with their Yorkshire Terrier, named Jonny Cash.

Bill McKenzie tried his hand at some line dancing to a bit of Lady Gaga. But as he jumped around the stage, the judges weren't impressed and showed him the door.
But as a flurry of red buzzers went off, it was time for the Luminites from 'just outside the M25' to grace the stage.

Jordan Clarke, 18, Ben Francis, 19, Stephanie Edwards, 18, and Corey Layzell, 21, all from London looked confident as they won over the judges and gained four yeses.
Alesha said: “Well, you’re a ready-made band. You’re fresh. I love the blend and the chemistry between you. You are solid, the beat boxing is wicked. Your voice is beautiful.”
Amanda added: “Luminites, it was amazing. It feels unique and the harmonies, perfect. It was absolutely a brilliant, brilliant audition.
Stephanie Edwards, 18, couldn't believe her luck with the comments the judges gave her and her band
Simon chipped in: “The song choice was absolutely genius, genius. Your vocals were outstanding. It’s very cool. By far the best audition we’ve heard today.”
But it was soon back to the weird and wonderful, starting with mother and son duo James and Shirley.
Aptly named Mother and Son, the pair announced that they wanted to become as famous as Des O'Connor before performing a rather strange act, consisting of singing and showing cards.
Mother and Son James and Shirley couldn't quite win over the judges with their bizarre performance
The audience looked confused but were soon won over when James started singing, but that wasn't enough to get them through to the next round.
Amanda compared Shirley to Dame Edna Dame Edna as Simon Cowell told the duo that the performance bought tears to his eyes, but not for the right reasons.
David continued to aggravate Simon Cowell by insisting to say yes to acts, including Mother and Son
Next up was double act The Duelling Pianos. Rob Russell, 55, and Craig Michael, 42 took to the stage behind a pair of pianos, playing a variety of tunes.
Simon wasn't impressed as usual, but the other judges looked like they were loving it.
David insisted that Simon enjoy himself and forced him to smile and dance, but he didn't look amused.

And much to Simon's dismay, Alice, Amanda and David all jumped to the feet at the end of their performance.

Amanda - who has already buzzed the pair out - then decided to take back her decision and put them through as did Alicia.
And despite Simon saying no, the other judges put them through much to the delight of the audience.
The next bunch of acts didn't impress the judges either after the four revealed that they were after more danger. Despite flaming samurai swords and head balancing, the judges didn't look pleased as they yawned away.
But if it was danger they were after, it was certainly danger they got with next act Aaron Crow.
Self-proclaimed mentalist Aaron Crow brought an element of danger to the show
The act - who stayed silent for the entirety of his performance - picked on the presenter after getting a couple of members of the audience involved during his audition on the ITV show.
He poured candle wax in his eyes before covering his face and slicing through a selection of props held by the nervous volunteers - including a pineapple balanced on Ant's head.
Aaron pulled host Ant McPartlin onto the stage to help him with his dangerous performance

The act impressed show boss Simon Cowell who said it was "great".
He said: "I love the idea of watching something where there is a possibility that someone actually could actually die, and the fact that it was Ant made it more exciting, I've got to be honest with you."
And it looks as though the rest of the acts were in for a tough ride as Simon seemed unimpressed with the average talent he was hearing.
However, bricklayer Robbie Kennedy - who taught himself the guitar - saved the day.

But he soon got it together and pulled it out of the bag with his rendition of The Goo Goo Dolls' song Iris, which gained him a standing ovation from the audience and all of the judges - including Simon!
After his performance, Alesha said: 'Robbie, you are so likeable. My heart is pounding. You just knocked me out. You have been blessed with a true gift.'
Amanda added: 'Robbie your voice is outstanding. You’re 22, where have you been? Do you sing when you work?'

Simon added: 'I’ve got to be honest with you, I wasn’t expecting that. Do you know what Robbie, I think that if you put that record out you would have a number one hit with that song. Loved it.
'You know what Robbie, the charming thing about you is that you don’t know how good you are. Congratulations. Four yeses.'
