As Donald Trump introduced his new Trump International Hotel in Dubai and Christina Aguilera's incredible set of pipes were bursting with song, Ali Larter strolled into the party in an amazing Robert Cavalli gown.

We do enjoy some Ali Larter for sure. She's a minimalist but always maximizes on color.This dress was just dreamy so we give her, not the Donald or Christina, a standing ovation.
