Gwen Stefani has been following a strict raw food diet
It's all thanks to a secret raw food diet.
According to a close pal, Gwen began the raw regime and ramped up her exercise programme to seven days a week in the run-up to her family holiday with husband Gavin Rossdale, 43, and sons Kingston, five, and Zuma, two.
?Gwen wanted to look incredible on her break, so she went on a strict 10-day cleanse,' says the friend.
'She only ate raw foods, which she found really hard as she loves cookies and pizzas, but she was determined to be able to indulge in the fabulous French food on offer.
'Her diet consisted of fruit for breakfast; raw meat or fish for lunch and dinner; and lots of raw veg.
'Gwen was also doing a daily super-high intensity cardio workout in the gym.'
The singer's diet allowed her to tuck into the meals on Roman's yacht, where world-class chefs cater to guests' whims.
?Gwen says she's been eating pain au chocolat for breakfast without guilt,' adds our source.
?She feels her cleanse was worth it to be able to do that.'
