The former 'Xtra Factor' hosts were hired to replace Dermot O'Leary on the main show this year and Caroline has revealed they're so excited that they've even been wearing matching outfits.

Asked if she was worried about being criticised for her fashion choices on the show, Caroline said: "A little bit because I'm usually a last minute person when it comes to getting dressed.

"Me and Olly have decided to co-ordinate everything ... Not too much, but he's really into it. He phones me like, 'What colour are you wearing today?' And I'm like, 'Yellow', and then he'll turn up at the door in a yellow shirt and I'm like, 'It's too much, Olly!' "

The 35-year-old presenter - who recently confessed she had a crush on Olly before they became colleagues in 2011 - admitted she wouldn't have taken the job on the main show if Olly hadn't been involved.

She told ITV's 'Lorraine: "It was the Olly Murs thing that did it for me, that made me want to do it."

And Caroline also admitted her mum still thinks the pair would be a great couple and is desperate for them to tie the knot.

Quizzed on whether she thinks there's any chance of a romance in the future, the blonde beauty added: "No! My mum still does. My mum says, 'Can't you marry Olly? Go on, it'd be perfect!' "
