The Project Runway host most recently shared two of her raciest Instagram pics to date; one of her sunburned bum and another of her under boob while laying on the beach.

Klum is definitely proving that you can still look smoking hot and have fun at 40, and that life does go on even after a heartbreaking divorce.

Klum's seven-year marriage to the singer Seal ended in 2012. They have four children together, three biological and one adopted from

Klum's previous relationship with Flavio Briatore.

Currently, Klum is dating her bodyguard Martin Kristen, who is often seen escorting her and her children on outings about town or on vacation. The couple seem like a nice match and it is obvious that the Victoria Secret model has gotten her groove yet. So Sexy!
