First, I am NOT 40!!! give me my due, I've got weeks and weeks 'til then. You could even count it in months!
Betty, Kulash is awesome, but I dunno about prettiest.
Actually, since it's "pretty" we're looking for, I have to agree with Mankie. David Sylvian is SO pretty. Does not mean I'd want to shag him...'too pretty' for a guy isn't my thing.
I tend to go for enthusiastic, fun and joyful, hence my undying devotion to Chris Murphy of Sloan, Mr. Grohl, and John Doe. None of them pretty, but certainly the finest fellows in rock!
