When it comes to staying slim, these celebrities will do just about anything.
Which celebrity eats baby food when she wants to lose a few points? And which actor ate nothing but fruit?
See below for 18 celebrity diets you won't believe!
Megan Fox: The Vinegar Diet
Who needs shots of tequila when you can take shots of vinegar? Megan Fox takes a shot of apple cider vinegar each day to stay healthy and reduce water weight.
Beyonce: Lime Juice and Maple Syrup
Beyonce's diet of choice is a Master Cleanse, which includes a concoction of lime or lemon juice, maple syrup, cayenne pepper, and water. How often? Try 6-12 imes a day for 14 days.
Ashton Kutcher: The Fruitarian Diet
To prepare for his role on the film, Jobs, Ashton Kutcher followed a diet that Steve Jobs did. Just like it sounds, the fruitarian diet pretty much only allows you to eat fruit. It's such a bad idea, it landed Kutcher in the hospital.
Christina Aguilera: The 7-Day-Color Diet
This diet only allows you to eat one color of food each day. Green one day, purple the next, and so on. Christina Aguilera is a fan of it, but I think most of us will pass.
Uma Thurman: The Raw Food Diet
Yep, it's just what it sounds like. This is a popular celebrity diet in which you can only eat raw foods -- nothing can be cooked above 115 degrees. For real.
January Jones: Placenta Pills
There's a science behind this one, but it still seems pretty weird. January Jones had her placenta turned into pills to help lose weight after giving birth to her son.
