He’s never really been asked this question in interviews before but I’m sure he doesn’t really have a preference but I have noticed that his past girlfriends were mostly brunettes. He’s a kindhearted and pretty open minded kind of guy so I’m sure he’ll be happy with any type of girl. He did mention though that he likes girls that he could talk deep things about with. Like the meaning of life and all that deep stuff. :)
I think the height isn’t really that much of a big deal but I’ve read about it from people who’ve met him or at least taken their picture with him that he’s not that tall so maybe he’s more for girls that aren’t as tall as him or at least shorter than him a little bit.
He just wants you to be nice, of course. :)
