Heidi Klum Flashes Fans on Twitter

Fully enjoying the power of Twitter, Heidi Klum posted a couple of fun photos for adoring fans today (August 7).

First was a pic of the German model draped in an American flag garment and taking a bite of some very cheesy pizza. The caption read, "Carb'ing it up!"

Later in the day, Klum must have been feeling even friskier, posting a vintage photo of the "Project Runway" host showing gold undies while leaning into a car door. She commented, "Whoopsie!" on the photo.

The 39-year-old mother of four is currently filming the tenth season of "Project Runway" for the Lifetime network. The long-running season airs Thursdays at 9/8c.
