Zachary is a whopping six-feet, four-inches. Yeah, that's tall. So dating someone who's super short may pose some technical issues. Enter the lovely Blake Lively, who stands five-foot, ten-inches tall. Not only would the relationship benefit Zachary, who wouldn't have to crane his neck down to kiss his girlfriend, but newly-single Blake would actually be able to wear heels. It's a win-win really.
