What's your definition of a "diva"? Aren't divas typically regarded as being temperamental or arrogant? I don't know that the men mentioned thus far have that reputation....well, except for Pascal.
If we're talking strictly about talented men, then I'd have to say Billy Porter springs to mind immediately.
Frankly, I hate how the word "diva" gets tossed around so casually. It's lost its meaning.
