Heidi Klum has broken the hearts of fans around the world by revealing she'll never pose in lingerie again.

The former Victoria's Secret supermodel, who turned 40 in June (13), insists she'll never strut her stuff in nothing but bra, panties and high heels again.

She tells Access Hollywood Live, "I wouldn't model with my underwear down the runway anymore. I think I would find it a little uncomfortable, maybe."

But she has no plans to give up modelling altogether, despite the fact she's now a busy international Tv personality fronting shows like Germany's Next Top Model, Project Runway and America's Got Talent.

She adds, "I still do photoshoots for (magazine) covers and different things or advertising stuff."
