Heidi Klum posts racy Instagram selfie wearing matching bra and thong

Va-va-voom!

"Project Runway" host Heidi Klum took to Instagram on Thursday to post a racy mirror selfie that shows her wearing a g-string thong, matching black bra and sexy strappy heels.

To avoid showing too much, Klum added star graphics over her derriere and some twinkling blue sparkles around her.

The captionless shot elicited a mixed reaction from Klum's Instagram followers in the comments. While some called the shot "sexy" and lauded her "ageless beauty," others slammed the former Victoria's Secret model for the post. "Maybe [a] midlife crisis," someone commented. "You just want attention," another accused.

It’s out! So thrilled to share my brand new Rather Go Naked Than Wear Fur campaign with @peta! I’ve dreamt of shooting this for as long as I can remember. 💘 If you don’t truly know what goes into making fur, please educate yourself. Fur is cruel no matter what. If you wouldn’t skin and wear your own dog, then you shouldn’t wear fur at all because all animals are created equal. Save our animals, save our planet and join me and #Peta in making more conscious choices ❤️🐺🦊🐻❤️

Klum's uber sexy post comes just a week after she essentially confirmed her new relationship with Tokio Hotel guitarist Tom Kaulitz. The rumored couple was seen arm-in-arm after landing at LAX last week.

Despite their 16 year age difference (Klum is 44 and Kaulitz is 28), the couple has appeared smitten with one another, having been photographed making out in public on multiple occasions already. 

Heidi Klum shares four children with ex-husband, Seal.
