The 28-year-old former 'X Factor' runner-up has admitted that she wants the two - who are replacing Dermot O'Leary on the upcoming series - to become romantically involved, as they have "great chemistry", despite the 31-year-old singer being loved up with Francesca Thomas.

Speaking at The Fragrance Foundation Awards 2015, held at The Brewery, London, on Thursday night (05.14.15), Rebecca told BANG Showbiz: (Dermot) has made his money, he's made his millions. He'll be alright. (Olly) will be good (as 'The X Factor' presenter). (He and Caroline) have the best chemistry, and I think we all love to watch them two, and we secretly want them to date. I think they've got a great chemistry."

The 'Nothing's Real But Love' singer also revealed that she thinks Nick Grimshaw - who has been heavily rumoured to be replacing Louis Walsh as a judge - will "add a new element" to the ITV talent show,

Rebecca said: "I think (Louis ) just wants to stay at home and watch ('The X Factor') on TV this year. He's a lovely person, he really is genuine and gets involved backstage.

"I've heard Nick Grimshaw's being lined up to replace him. He's quite young, cool, all the young kids love him, and he'll add a new element."
