The blonde model was seen in the Mojave Desert in California on October 11, flaunting her toned bod during the shoot. In the pics, Joanna is wearing a see-through gold dress with little underwear underneath. In the pics where she's not topless (boring!), she's still looking hot in red bathing suit bottoms, a striped crop top, and a hat.
