Alessandra Ambrosio smiles over her right shoulder

Model (or supermodel, you pick) Alessandra Ambrosio smiles over her right shoulder at photographers while wearing some kind of crazy-wonderful white and gold gown. The photo date and event are, sadly, unknown. We're going to take a wild guess and say that this is one of the Oscar parties that Vanity Fair magazine has often held on Academy Awards nights. That looks like it might be the V and the A right behind her.
