Heidi Klum slams models in Royal flash for wearing her underwear: 'It's not cool'

Uh oh! Heidi Klum isn't happy about a publicity stunt involving three underwear models posing in her undercrackers line outside British tourist spots.

Over the weekend, the three stunners (check them below) braved the cold spring weather to pose next to the Thames and Buckingham Palace. As you do!

And considering the trio were all in Heidi Klum Intimates and she was in town on a promotional tour, all fingers were pointed firmly at her.

But the 41-year-old former model hit out on Instagram on Monday night, saying: "Nearly fell of my chair when i saw this. Who did this??? Not me!!! NotCool."

Well, now, it begs to question...did someone in Heidi's team go ahead with a PR stunt without her approval? We can sense a sacking.
