There’s always something going on in Heidi Klum's world, and the German supermodel’s latest project is a fun and flirty new commercial for Jordache jeans.

Klum is the face of the classic denim brand, and she posted a video clip to her Facebook page along with the caption, “Part one of my new Jordache commercial!”

The video features Heidi’s backside bobbing all over the screen as she walks through a neighborhood while the Bee Gee’s classic track “Staying Alive” plays in the background.

Jordache Enterprises president Liz Berlinger told press, "We are excited to be working with Heidi Klum for the fourth time. Heidi is a true Renaissance woman who inspires us all as she balances life as a supermodel, TV host, business woman and mother. Heidi's fashionable style and sexy confidence embodies what the Jordache brand is about."
