It's hard to avoid her. Beyonce' is everywhere and she has quite a figure. Combine that with news that she dropped a lot of weight fast for her starring role in Dream Girls, and you've got a lot of people wondering what her secret is.

She's known for her dangerous curves but recently Beyonce Knowles made news when she slimmed down for her role in the blockbuster film "Dreamgirls." The star shed 20 pounds in 10 days on the "Maple Syrup Diet".

For some people, this kind of drastic weight loss sound like a dream come true, but personal trainer Jack Douglas says that kind of loss isn't the norm for regular women.

"What I've found is that people who come to workout with me have to have a more realistic expectation of working out for a longer time," says Douglas.

But what exactly is Beyonce's Maple Syrup Diet? It's a liquid fast. It's also known as the Lemonade Diet or the Lemon Cleansing Diet.

Here's the recipe:

* 3 quarts of water
* 1 cup of lemon juice
* 1 cup pure maple syrup or molasses
* 1 teaspoon cayenne

and you drink 8-12 glasses a day.

Knowles admits the diet isn't the best way to lose weight. She also admits that as soon as her movie wrapped, she gained the weight back.
