Simon isn't the North Weezy rapper's biggest fan: he gave her a 'no' at her audition, and has claimed she can't sell records.
But if his comments on last night's Xtra Factor are anything to go by, Honey's charm has finally won him over.
Sharing his thoughts on Motown Week, he said: "That was so good tonight, the show. I loved it, I love that theme, I thought they all stepped it up. It was just like being at a Motown party, brilliant.
"You know what, I’ve kind of got a crush I think on Honey G! It’s a nice crush!"
Sinitta and Lauren Silverman may want to watch their backs!
On the other stand-out acts, Simon added: "I loved 5AM, I loved my girls tonight, so many stars. I love that."
Simon didn't love all the acts, however. He described Ryan Lawrie's performance as "mechanical" and "old-fashioned", adding: "This was a mistake and I really feel bad for you."
Freddy Parker and Saara Aalto are the favourites to leave during tonight's results show at 8.00pm on ITV. It will feature guest appearances from Little Mix and OneRepublic.
