Madonna offers weight loss tips to Kelly Osbourne

London: Pop star Madonna has helped ‘Fashion Police’ host Kelly Osbourne drop a dress size by giving her exercise and diet tips.

The two have worked together on the ‘Girl Gone Wild’ hitmaker`s clothing range Material Girl, and the singer has been advising Osbourne on diet and exercise to help her shed weight she gained earlier this year.

"Madonna`s helped Kelly get back to a size eight. Kelly does the Ballet Barre workout five days week - she loves the dance element and can see how it`s changed her shape," quoted a source as saying.

"Madonna`s also encouraged her to eat in a more macrobiotic way - cutting out wheat, artificial sweeteners and cheese. Kelly`s avoiding carbs to beat bloating and has been eating boiled eggs for breakfast, grilled chicken salad for lunch and fish with steamed greens for dinner," added the source.
