The show's new host, who is now 35, suffered embarrassment at Wednesday’s (22 July) auditions, when Cheryl Fernandez-Versini made a jibe about her love of younger men.
After 20-year-old hopeful Ollie Marland drew criticism for his dated performances of Wham’s ‘I’m Your Man’ and Take That’s ‘A Million Lovesongs’, Simon advised him to go out for dinner with host Olly Murs to learn how to be cooler on stage.
As Simon asked if he would be up for it, Cheryl chimed in: “I know Caroline would. Right Flackers?"
But Simon didn’t seem to think this was a wise idea, adding: “If you’re going to go out with one of them, it's Olly. Trust me."
Oooh, so much subtext.

Caroline’s relationship with One Direction star Harry became a national talking point in 2011, owing to their 14-year age gap, and the fact that the singer was just 17 at the time.
She went on to find love with music manager Jack Street, who is eight years her junior, but the pair split while she was on ‘Strictly Come Dancing’ last year.

However, recent reports suggested that the pair have reunited after they were spotted getting cosy at Glastonbury last month.
