Like most female celebrities, Christina Aguilera has been scrutinized for her body size, deemed too thin during her "Dirrty" days in the early 2000s, and then labeled overweight following her 2010 divorce from Jordan Bratman.

Last March, after a few heavier post-divorce years, she began showing off a slimmer body, clearly sticking to a healthier diet and exercise routine. By September, she reportedly had lost 49 pounds, thanks to the help of a personal trainer and a strict diet that includies limited alcohol and a balanced meal plan, Life & Style reported.

Aguilera starts her day with healthy fats and protein such as an avocado, blueberries and turkey bacon. For lunch, she eats chicken breast and a salad filled with bacon. (Chicken breasts are widely viewed as a great source of lean, low-fat protein.) And instead of picking up unhealthy snacks, the singer relies on shrimp cocktails and celery with almond butter.

But once female celebrities lose weight after negative media attention, some take it too far. This may be the case with Aguilera, after she showed off extremely slim legs and a small waist during the People’s Choice Awards Wednesday night. During a humorous introductory skit, the 33-year-old played a waitress, wearing a sequined gold and red uniform and red platform heels. She acted alongside the show’s hosts Kat Dennings and Beth Behrs, who play waitresses on their show “2 Broke Girls.” Do you think she has lost too much weight?
