From her job as Austin Powers' attractive sidekick to her role as the Upper East Side's No. 1 cougar on Gossip Girl, this British actress's sleek physique has never faltered. (Video: This model is also a karate champion!) So, how does the 47-year-old star stay so slim? She once told the Daily Mail that she drinks at least six cups of watercress (this veggie has few calories) soup a day whenever she wants to lose a few pounds. Who is this soup dieter?

To transform her body, this ultra-sexy movie star relies in part on apple cider vinegar.

What's the latest on those pregnancy rumors?
This impeccably coiffed actress may be childless, but that hasn't stopped her from stocking her pantry with baby food. According to reports, this Friends star feasted on 14 servings of baby food a day when preparing for a movie she made with Adam Sandler. Who is this baby food dieter?
She's also a practitioner of this hybrid yoga regime
Long before vampires were cool, this actress was kicking their butts as a super buff vampire slayer. Sure, karate and kickboxing were part of the leading lady's regimen, but in more recent years she's rumored to have tried the cabbage soup diet, which involved eating unlimited cabbage soup (check out the diet details) plus low-calorie fruits and veggies.

Around since the 1930s, this diet involves eating half a grapefruit before every meal and hinges on the idea that grapefruits contain an enzyme that boosts fat burning (what is it?). According to a number of reports, this former Calvin Klein model was one of the fad diet's many celebrity fans. Who is this citrus-eating celeb?
She'll co-host upcoming Drama Desk Awards
We shouldn't be surprised by any of this eccentric pop star's antics by now -- but we were stunned to read about the so-called drunk diet, pioneered by her ex-boyfriend, who even wrote a book about it (shop for it). The singer says she drinks whiskey while she works, but then commits to exercising -- even when battling a hangover. Here's to hoping this diet is more of a publicity stunt (as many people speculate) than a lifestyle. Who is this tipsy dieter?

Adding color to your diet can help ensure that you're getting a variety of nutrients. This weight-loss plan takes that idea to the next level. (Related: The Best Ways to Add Color to Your Diet) Each day the dieter eats a different color; so, she'll eat white foods on Monday, red foods on Tuesday and so forth. The offbeat regimen has supposedly attracted this big-voiced pop star and reality show judge. Who is this colorful eater?
Is there tension on the reality show set?
This sultry singer-turned-actress invented the word "Bootylicious" with her smoking bod. After being cast in the motion picture Dreamgirls, the songstress turned to a liquid lemon juice mixture to quickly slim down for her role. The diet (or starvation plan) requires six or more servings of the juice a day as well as a saltwater flush and herbal laxative. (Related: A Diet Cleanse That's Safe--and Really Works) We hope her then-boyfriend wasn't around to see -- or hear -- what was coming out the other end. Who is this master cleanse celeb?

We're beginning to lose track of all the weird ways this actress stays slim. She has been known to follow a macrobiotic diet, a strict, mostly vegetarian plan. Then there's her GOOP cleanse, a 21-day detox plan that allows only one meal a day. Even prisoners are given more food than that! The weirdest part of all of this is the way she chews her food, reportedly chomping each bite 13 times. Who is this multi-dieter?

This is one of the scariest weight-loss plans out there. The dieter consumes only protein shakes mixed with powdered egg, washed down with a gallon of water, while continuing to exercise once or twice a day. And that's just the beginning. Right before runway time, she'll stop taking in liquids altogether! Emaciation may be a popular runway look, but in real life it's just plain dangerous. Who is the supermodel who follows this diet?

We love guilty pressures, so naturally we were intrigued by The Cookie Diet. But don't let the title fool you. On this plan, dieters eat up to nine 60-calorie cookies a day, breaking for the hunger-suppressing treat every two hours. Talk about a cookie coma! One reality star used it to drop pounds she had put on with her binge-drinking lifestyle. Hint: Her name rhymes with cookie. Who is this cookie-eating celeb dieter?

Don't confuse this weight-loss strategy with the Grapefruit Diet--actually eating the fruit is too passé for this fly girl. We hear she prefers to carry a vial of the oil extract in hopes that the aroma will kick liver enzymes into high gear and promote weight loss. Sounds ridiculous, right? Which celeb is using this diet?

Possibly one of the only Hollywood diets not to focus on weight loss, the Fish Facelift, or Perricone Diet, calls for hefty amounts of salmon to reap the anti-aging benefits of omega-3s (what are those benefits, exactly?). We've seen worse diets, but eating salmon at every meal gets old quickly. This Sex and the City star is rumored to follow the plan. Who is this sexy celeb?
She earned Broadway honor
We hear this material girl prefers her food fermented. More of a science than an actual plan, her chef has created a diet that's high in fiber and laced with "good bacteria." The theory is that the bacteria will ward off cancer and help with food digestion by promoting the growth of microbes in her poop. Yes, her poop. We hope we never again have to read about this star's colon or bowels. Who is this bacteria diet follower?

When we heard about this starlet's diet, we thought she went mad! Following the birth of her son, she had her own placenta dried, crushed and put into capsules -- and she ingested them in an attempt to shed her baby weight. Who is this placenta pill popper?
