The 35-year-old's performance, in which she grabbed her crotch as she invited listeners to "let me search it", divided judges.
The turn won her a burgeoning fan base on Twitter , but had some speculating whether she was for real or a parody act.
However, the sunglasses-sporting Anna Georgette Gilford - to give the rapper her real name - insisted she was 100% genuine.
"There is nothing fake about me. I just say middle finger to my haters. I’m stepping up to the streets with the material that I’m writing," she told the Mirror.
The recording artist, who is also a DJ and producer, claimed she brought a breath of fresh air to the show, insisting it was time for judges to "choose someone who is making innovations".
Anna, who refers to her home town as North Weezy, is a recruitment consultant for her own company but said the business was not doing well and she saw the talent show "as a way out".
Honey G's music is a hit with her mum Yvonne, but Anna says the 68-year-old retired classical pianist is less enamoured by the swearing.
