I'm a real spice fiend, so I love Thai food and south Asian food," she told us. "My family are from the Caribbean so I love that as well. I tend not to go to restaurants to eat that kind of thing though, I prefer to cook at home."
There's a lot more to Dunn than solely modeling - in February she launched a Marks & Spencer childrenwear line, inspired by her son, called Lil' LonDon. She's currently working on the next autumn/winter 2016 collection and is set on developing it slowly.
Having starred in campaigns for Balmain and Burberry, Dunn is now in a position to choose who she works with carefully - the latest brand being US fashion brand Kate Spade, who opened its Regent Street store yesterday.
"I've always been a big fan of the brand," she said. "They support a lot of interesting women and it's important to try and get women to stand together and support each other."
One of the more recent additions to Dunn's CV has been her foray into acting. She made a cameo in the recent Zoolander 2, which starred Ben Stiller and Owen Wilson, alongside a host of fashion stars such as Kate Moss, Anna Wintour and Marc Jacobs.
"Ben's such good fun to be around," she said. "I'm such a fan of his, everyone - people like Anna Wintour - just took the piss out of fashion. It was so much fun."
