When you look as stunning as Project Runway host Heidi Klum, you can wear anything you want ... even if it's a t-shirt with a heart!

The gorgeous mama of four strutted her sexy bod in Venice while filming episodes for the new season of the hit Lifetime reality show.

We're lovin' how Heidi paired her skintight leather pants with a casual shirt under a studded leather jacket ... and of course, black Louboutins!

This season will feature a number of guest judges including Bette Midler, Susan Sarandon, Miranda Lambert, John Legend, Joan and Melissa Rivers and Emmy Rossum.

Can't wait to watch!
