Honey - real name Anna Georgette Gilford - has thrilled millions of viewers with her entertaining performances, even winning over Simon Cowell.
But it seems just as many reckon she's fake, and some even suspect she's 'catfishing' the show.
It turns out Sinitta is in the latter camp, telling the Huffington Post this week that she's suspicious about Honey's upbringing.
"Her mother has a middle class, English accent, she’s very pretty," the 'Toy Boy' singer explained. "She’s not at all ghetto, she doesn’t say ‘yo’ and ‘what’s up’ and everything.
"So I don’t know how Honey G has developed all these traits.
"I think she’s faking it, but I think she believes. I think she has reinvented herself as a black American ghetto rapper."
However, Sinitta also dismissed accusations that Honey's act is racist.
"That’s like saying Ali G is racist," she commented. "Maybe Honey G is the musical version of him."
Honey didn't seem too bothered about the backlash on This Morning yesterday, responding: "All these people are just haters.
"They need to check themselves, they're never gonna get anywhere while they're preaching all this hate."
The X Factor continues tonight at 8.00pm on ITV with Fright Night week, when Honey will be singing the Men In Black theme.
