Heidi's Sexy Snaps

Heidi KlumNothing says "yummy mummy" like posing for a set of saucy pics. 

Just ask Heidi Klum.

The supermodel sizzles in a new Jordache ad campaign, where she's sporting a pair of skintight denims, boots, and little else.

Gulp.

Do we need a lifetime membership to the gym to look like that?

Apparently not, according to Heids.

The model mum told People: "I have three children.

"That keeps you busy all the time. We work in the garden. We jump on the trampoline. I just started playing tennis with my husband.

"We climb in the tree house with the children. We go to the park and feed the ducks. We are always mobile."

Of the sexy ad pics, ever-modest Heidi said: "He (Brett Ratner, who took the pics) had a lot of assistants. So I don't have to do that much. They all make me look good."

And it's not just Heids looking good in denims. On her man, Seal, she said:

"I like him in jeans. I like him in anything. I like him without anything."

Steady on there, Heidi.
