Don't They Know You Don't Double Dress Divas?

Dolce and Gabbana! How could you? You, of all people should know better.

Dining with the designers, Domenico Dolce and Stefano Gabbana, in Italy, Madonna was quite pleased to be wearing an exclusive D&G original. After all, the Material Girl expects the best because, well, she's a raging diva.

So, I wonder how the dinner chat would have gone if, say, well, maybe a little birdie whispered in Madonna's ear that, on that very same night, just a few miles away, Whitney Houston was......

Wait for it.......

.....wearing the exact same dress; also gifted to her by D&G?

Whitney was also given the figure-hugging gown when she made her grand return to the spotlight. She was launching her new studio album I Look To You in London's for what she hopes will be the beginning of a triumphant comeback.

So, who wore it best?

And who do you think threw the bigger diva-tantrum when they found out that they weren't exactly in a one-of-a-kind, exclusive D&G?

Keep in mind that Madonna is scrappy, but don't forget Whitney's a crack-is-wack diva.
