A TEENAGE couple who became world famous after BOTH switched gender have split up - to the dismay of an army of fans and followers. University student Katie Hill, 19, who was born 'Luke', and high school student Arin Andrews, 17, formerly 'Emerald', fell for each other after bonding through their transitions between the sexes. Their fight for gender recognition was made even more difficult by the fact that both lived in small communities in Oklahoma, part of America's 'bible-belt', where traditional views are said to be more popular. The quest to highlight gender issues gave them a 'unique bond', while their amazing looks and honesty made them champions of the young transgender community in the US. But sadly the two have decided to split saying they want to focus on 'having fun' and 'enjoying young adulthood' as singles. The pair have revealed that many of their online followers have expressed disappointment over the separation but most also wished Arin and Katie well wishes for their futures.
