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.

Today is National Leathercraft Day, National Relaxation Day and National Lemon Merengue Pie Day. It’s also the 9 month anniversary of my hysterectomy. I’ve never celebrated the 9 month anniversary of anything and I realized last night why that number feels so funny- I won’t ever do it the way I planned to. My body is mostly healed and every day I find a new bruise on my heart, but today I offer myself gratitude: from the most pained place, I somehow knew to choose myself. The purest glint of who we are and know we can be is always available to us, calm and true at our center. My friend Paul named my uterus Judy, and when she was being uppity we called her out, hence the tattoo on my ribs, which hurt like fuck even through the pain meds: #RIPJudy. Today I give thanks for Judy, for her graceful exit and for this body, which is stronger than I’ve ever given it credit for. Happy Giving Birth To Myself Day.

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.
