The X Factor host famously enjoyed a brief relationship with One Direction star Harry when she was 32 and he was 17.
Speaking to Radio Times magazine, presenter Caroline said: "I just laugh. It's funny. I'm not mugging a nan in the street, am I!"
And on the subject of romance…
Caroline admitted to the mag that behind the scenes at Strictly Come Dancing definitely isn't as hot and sexy as people may think.
She won the show last year, partnered with Pasha Kovalev.
Chatting about the whole Strictly curse of professional dancers and contestants falling for each other on the show, she said: "I don't think anyone really thought anything was going on between me and Pasha!
"You're not at your most attractive during that show… during rehearsals you're sweaty, smelly, you've got bunions, you're tired and grumpy… it's not as sexy as people think it is! And anyway, all of that attention's not that bad!"
Caroline can currently be seen hosting the revamped series of Love Island, which airs on ITV2. She'll co-host the 12th series of X Factor with Olly Murs later this year.
