Talking to omg! Tulisa, Lucy Spraggan and Jade Ellis all admitted that the song is still in their heads, months after Ella performed it.
Lucy admitted: "Ella's first song has been stuck in my head," with Jade adding: "We've been singing it all day!"
Mentor Tulisa also confessed to loving the song saying: "I'm doing it too, I'm around my house doing it-I even found myself singing it the way she sings it. It's hilarious!"

This year's X Factor has seen an influx of musicians taking part leading to some critics questioning whether the show is the correct platform to nurture this sort of talent.
Lucy Spraggan has rubbished these claims, saying that the format of the show has evolved to suit acts such as herself and Ella.
She explained: "The thing is this year, and if they [critics] haven't picked up on it then they're not studying the show properly, to let people like me and people like Ella in they [the producers] wouldn't then go 'we're going to go back to doing things that are going to put you on the spot and make you look bad'. "
"It's a game changer this year, bringing in the element of musicians. I'm putting my trust in this competition and I think they are putting their trust in us."
Agreeing, Jade pointed out that the majority of the finalists were in fact singer/ songwriters.
She said: "Most of the people who are left in the competition, pretty much all of us write. If you think that what you have done is good enough to get it out and it fits into a theme then that's how you should be able to introduce your own songs."
Lucy did however admit that not all of her quirky songs would be right for the competition.
She admitted: "I've got over 200 songs and I don't think that all of them would suit the show- I couldn't come on the show and sing a song about Jeremy Kyle."
