His mother appears to be white--white as Wonder bread white. His dad has a vaguely ethnic look to him, but he doesn't really look Asian to me--perhaps Native American, Hispanic, or mixed race? I think David looks a lot like his dad--they have the same eyes and overall facial structure--but David is leaner.
If I were to judge David by his looks alone, I probably wouldn't be too excited, but when do we ever fall for someone based on looks alone? It's how people carry themselves and interact with other people that really matters. Having seen his show, he comes across as a total sweetheart with a great, positive energy. He's got a great smile and I love that twinkle in his eye. I find him absolutely adorable.
