Robbie Rogers reveals many things in his new autobiography Coming Out to Play including the surprising fact that he was a twin.
It's something he sensed from a very early age without anyone ever telling him.
'One day when I was six or seven years old I asked my mother if I had a twin brother,' he writes.
It's a fascinating story he let his mother, Theresa Rarick Rogers, write about in the book.
'I never said a word to my children about Robbie's twin, so I was shocked when Robbie asked me about his twin brother,' she writes.
