She may have had a glamorous makeover and showcased a new set of teeth but it seems X Factor judge, Tulisa Contostavlos, hasn't been forced onto a strict diet.

The N-Dubz star was more than happy to prove that she eats what she wants as she stuffed her face with fish and chips on the Jonathan Ross show.

Showing she's nowhere near being a diva, the 23-year-old star sat on the famous host's sofa with a greasy paper bag of chunky chips and enjoyed her battered cod.

One hell of an appetite: Tulisa Contostavlos enjoyed a bag of fish and chips whilst appearing on The Jonathan Ross Show on Saturday October 1

Wearing an all black outfit the singer looked fantastic as she took time to talk to Ross.

Sporting black skinny jeans, with a low cut vest the small star completed her look with a sky high pair of unusual black stilettos and wore her long hair in a slicked back style.

Sitting beside her was her fellow judge, Gary Barlow who also enjoyed some chip shop carbs.

Looking good: the 23-year-old chose to wear all black and sky high heels for her interview on the new ITV1 chat show

But it seemed that Tulisa enjoyed her take away a bit more than her older co-star, as throughout the pairs interview, the Playing With Fire singer looked happy and in a playful mood.

Probably talking to Ross about her new found fame as a judge on the talent show, Tulisa was seen giving him the thumbs up whilst showing off her new set of pearly whites.

Last week it was revealed that Gary would me mentoring the boys of the contest, whilst Tulisa would be looking after the groups, which is possibly what prompted her to show off her muscles to the 40-year-old star.

Thumbs up: Tulisa was really pleased to be mentoring the group category on this year's X Factor and is determined to win

The strong-willed Londoner is definitely determined to ensure that a group will win this year - which would be a first on the show.

Or maybe her show off pose to Gary was her way of showing what some greasy food can do to you.

Believe it or not, the slim star is crazy about food and constantly references to it on her Twitter account.

Look at my muscles! The N-Dubz singer showed Take That star, Gary Barlow, how strong she really is

Only the other day, she was tweeting about her need for a takeaway saying: 'I'm not guna lie, my head hurts, I need sum1 2 open this bottle of water cus I don't have the strength!then feed me either chinese or pizza.'

But earlier on that day she'd fancied something rather different, telling her followers: 'Wait I'm getting the sudden urge 4 fish fingers And spaghetti hoops, also wana watch the labyrinth with david bowie while I eat them lol.'

Perhaps this is the reason the TV presenter gave the duo some fast food in the first place.

Also on the show talking to Ross was comedian Alan Partridge and Scottish actor, Ewan McGregor with music provided by Cee Lo Green.
