Caroline Flack: Tulisa eats two dinners!

Caroline Flack has the most famous legs in the country so it's no surprise the stylists at Heat magazine wanted her to show them off to full effect. In the current issue, the Xtra Factor presenter shows off her stunning pins in a cute all-American girl outfit as she dishes the dirt on the nation's favourite singing competition judges; the X Factor judges!

On Tulisa, she said: "Tulisa eats two dinners.

"And she eats so slowly. The whole table will have finished and she'll still be on her dinner. Her first dinner, I mean; she's got the second one to come."

She added that Tulisa is a "girls' girl" and that she "would always have your back".

"In a mother hen way, she looks out for you," she said. "She's very soft, much more than you'd think."

Not that we ever doubted the Take That star's wit, she said of Gary: "[He] is a lot funnier than people think. He's got a dry sense of humour."

And who on the judging panel has the best impression of a TOWIE star? That would be Nicole!

"Nicole is quite good at doing an Essex accent. And she laughs at herself. I still want to grab her hair sometimes and mess it up. She always looks perfect.

"If you want gossip, go and ask Louis. He knows everything. I always try and get stuff out of him."

Caroline, who famously dated One Direction star Harry Styles (who was 17 at the time to her 32), also revealed that she likes a little on-screen flirt with her 'step-brother' Olly Murs.

"I say 'step' because it means we can still have a little flirt on-screen. Because if you flirted with your brother it would be weird. I don't think we fancy each other, we just flirt..."

While showing off her legs in the photo shoot, she explained the truth behind her enviable body.

"I'm not a fitness buff," she insisted. "I've got exactly the same legs as my mum. I like having curves. I will never diet. I love burgers and I love chips. I like good food and I'll eat until I'm full. I have a panic week in the gym two weeks before the X Factor starts, but that's about it."

We're not sure if we can quite believe that, Ms Flack!

The full interview appears in this week's heat, on sale now (Tuesday). Watch Caroline on The Xtra Factor, ITV2, Saturdays and Sundays, and check out her X Factor column, only in heat.
