I never found Peter Martins handsome, and Carlos Acosta is (I'm afraid) not very attractive, at least to my eyes.
Very good-looking from ABT's current roster is Grant DeLong. Casting him as Paris alongside Hallberg and Paloma was a mistake, as I couldn't understand why she'd turn down Grant for David.
I also like Craig Salstein for his unaffected American good looks.
(My post made it here, but the server had an apparent glitch - probably it was mad at me for speaking ill of Carlos and Peter - and it didn't update the index or list of Last Posts.)
