Heidi Klum has been having her ups and downs lately, at least in the weight department.

The voluptuous, yet slim, Victoria's Secret model, ballooned, as do most women, while pregnant, and then labored, pun intended, to knock the superfluous poundage off.

In keeping with the tenets of her generous Victoria's Secret contract Heidi had just 30 days to get back into fighting shape, which for her meant being able to model underwear. What a tough job!

The Supermodel claims that getting the weight off was effortless, and happened almost on its own. She also stated that giving birth was nowhere near as painful as she was led to believe.

She said: "I thought it would be more difficult, but it was the most amazing feeling."

Let's see, she's young and beautiful, she's thin and healthy, yet shapely, makes tons of bucks, is a happy Mom, and is dating singer, Seal.

Lucky Heidi, Don't you just hate her, girls?

But, aha, now she's up for a real challenge.

Klum has just signed on as a representative with McDonald's, and I wonder if she's required to eat a certain amount of Mickey's haute Cuisine?

We'll have to wait and see if Heidi becaomes a McNugget muncher, or develops a French fry fanny, or hamburger heiney.
