Alessandra AmbrosioThe gorgeous Alessandra Ambriosio looked nothing short of perfection in her Queen of Hearts costume last weekend. The Victoria Secret Model was inspired by Alice in Wonderland for this outfit, and it's safe to say that she definitely outdid the part. From her stunning makeup and hair to her sexy costume, Ambriosio takes the cake for the most beautiful celebrity costume so far. [Photo via @alessandraambrosio, via]
