Heidi Klum In Lingerie At 43

Heidi Klum doesn't just run her own fashion line of Heidi Klum Intimates. She models them, too! The 43-year-old entrepreneur is seen in these shots laying out some very hot looks for her lingerie collection, plus her other brand — Heidi by Heidi Klum!

It's the fourth campaign for her collections, and another triumph for the smart businesswoman who can still hit the runway! "I am thrilled with this latest collection and can't wait to share it with our customers all over the world who swear by the fit and intricate beauty of our styles," said the model, adding: "I'm so proud that we're available in over 2000 stores!"

Heidi still finds time for romance while promoting her empire, though — thanks to her 29-year-old boyfriend Vito Schnabel! The art dealer has been with Heidi for several years now. Still, The National ENQUIRER has learned the two aren't any closer to the altar!

"Heidi likes the way things are," a source told The ENQURIRER. "She feels that her career and her kids [three from first husband Seal] don't leave room for another marriage!"

But don't feel too bad for Vito. The ENQUIRER caught Heidi ditching her dress while the two were on vacation back in April — and her younger man still seems plenty interested in his older woman!
