Natalia Vodianova was in high spirits last night at the pre-party for her Love Ball tonight in Monte Carlo. She posted a video on Instagram that showed her dancing in front of fireworks across the bay, with Derek Blasberg and Mario Testino.

The ball, which takes place this evening, raises money for the model's charitable foundation The Naked Heart Foundation, which helps disadvantaged children in Russia. Guests will be able to bid at an auction for prizes that include an exclusive outfit designed by Karl Lagerfeld, and a private fitting for a one-off couture gown with Raf Simons. The bar's high then.
