It's not the first time the 80s pop queen has opened up about her famous ex.
She revealed on Celebs Go Dating on Monday how Simon is protective over her and her love life.

They went on to enjoy a 20-year on/off relationship before he found love with her best friend Lauren Silverman.
Now Simon has taken on a "protective, big brother" role in Sinitta's love life.
"Simon was surprised I was doing Celebs Go Dating," Sinitta told The Sun ahead of tonight's series 11 launch.
"He said ‘well, anyone they fix you up with I’ll have to vet them.’
"Simon’s got that protective big brother thing which was very sweet. "
She added: "I would like anyone I’m with to get on with Simon because obviously he’s one of my closest best friends.
"We want to hang out and we’re Godparents to each other’s children. It would definitely be nice if they got on, but we’ll have to wait and see."
