Scarlett flashes her rock

A very sparkly Scarlett Johansson shows off her newly acquired rock while being flanked by Domenico Dolce and Stefano Gabbana at the Metropolitan Museum of Art's Costume Institute Gala in New York City. Her dress is a Dolce and Gabbana, just like her photo partners.

The dress sort of looks like a slip that goes under a prom dress to me, but hey, the girl is happy so I guess I'll cut her some slack.
