And Simon Cowell said: "I don't know what just happened.
"But here's the weird thing, I loved it. I just really like you. I thought you weren't serious when you came in but now I realise you are."
Honey told host Dermot O'Leary after closing the first live show of the series: "I'm just having the time of my life, I just don't want it to end."
But can Honey escape the first elimination on Sunday night?
Speaking before the live shows, Honey said she wanted to prove her hates wrong.
She said: “I know some people have been saying they don’t think I’m real and that I’m a prank that’s been set up by the producers, but those haters need to check themselves because I AM the finished article.
“I might not have the most amazing voice but I’m a heavyweight rapper, singer and producer and I write my own lyrics, so I’ve got real skills to bring to the table. To be regarded as a joke is really insulting.”
Speaking about her first live performance, Honey added: "I would like to deliver a track that’s gonna make the hairs on the backs of peoples’ necks stand up."
