Jameela Jamil has defended Demi Lovato after the singer launched a tirade against owners of a frozen yogurt shop in Los Angeles. The Cool for the Summer star - who has battled drug addiction and an eating disorder - urged officials at The Bigg Chill in Los Angeles to "do better" as she felt they were pushing diet culture by making sugar-free and low-calorie foods prominent, and she vowed to shame other stores she felt were doing the same using the hashtag "#DietCultureVultures".
