Now it is Sadie Frost's mother, Mary Davidson's duty to take care of Kate Moss's diet.
Mary, who is now Moss' live-in nanny, not only looks after the supermodel's five year old daughter, Lila Grace's diet but she makes sure that the catwalk queen, who regularly stumbles home in the early hours after a heavy night of partying, follows a healthy diet too.
The 58-year-old was stunned to see Moss' greasy eating habits, which she believes are taking its toll on her skin.
Therefore, she took the task of becoming the 34-year-old model's diet guru and made a list of culinary dos and don'ts and is ensuring Moss sticks to them.
Moss has now given up her morning-after-the-night-before breakfasts of fried bread, eggs and bacon in favour of muesli and is embracing salads, oily fish and smoothies.
"Kate is responding well to having a surrogate mother and is in agreement about her bad diet," The Daily Express quoted a friend, as saying.
"The bacon butties have flown out the window and she's even started juicing," the friend added.
