Gigi Hadid has admitted she eats cheeseburgers more than once weekly.

The 20-year-old beauty claims that because she works out she is allowed to indulge in fast food whenever she fancies it.

She said:''I love a couple of cheeseburgers a week.''

The American model - who was announced as Australia's ambassador for label Guess - says when she doesn't have much modelling work on she doesn't follow a diet so rigorously and allows herself to the odd naughty meal.

She told Sydney's Nova 96.9 FM: Sometimes there are jobs that I have to plan for and take a month in advance to just focus on eating healthy and working out more. But as long as I'm working out I love a couple of cheeseburgers a week.''

Meanwhile, the fashion icon - who is best friends with Taylor Swit and Kendall Jenner - recently opened up about modern models are getting to experience what it was to be an ''it girl''.

She recalled to E! news: ''The pictures of them [it girls] at events together, backstage together, are so iconic and it's really cool now that I feel there's a group of girls again that are gonna create that. Like the whole 'squad goals' thing is a very big thing right now. I feel like as models, we're kind of getting to experience what they did.''
