How much can you truly know about your own family. They answer for Kenzie was not well. She is the twin sister of crown prince Christian of Denmark and since the age of 15 she has been famous popstar Luna. None of her family knows she's Luna which is ironic since her little sisters Isabella and Josephine are obsessed with her music. King Fredrick and Queen Mary just thought she like to travel not even her twin brother knows she's Luna. She wore a wig and colored contacts when she was Luna so no one knew and it felt good to have a secret of her own growing up as royalty. She was sitting at the dinner table with her parents and siblings her younger sister Isabella was turning 18 soon and she was planning her party she was going on and on about what she wanted and then she said something that made 'Luna' choke on her food almost. Isabella: Do you think we could get Luna to come I know she was in England recently with her boyfriend Charlie Hunnam
