Jonas Royalty

REPOST!!!!!
Ava Denise Jonas is the twin sister to Paul 'Kevin' Jonas II, and when she graduated with her twin at 18, her dream was to go to college while her brother and younger two Joseph and Nicholas would start their band The Jonas Brothers.
Five years later, Jonas Brothers are huge, and Ava was in England going to college, and wants to hide from the world because the fans know that they have a sister. But it's hard to hide when she's in the British news because she's been seen hanging out with the Royal family, especially young Prince Harry of Wales, given name Prince Henry Charles Albert David Windsor.
It's Christmas time, so Ava goes back home to surprise her family, and to surprise her family with an announcement. How will her family take the news, and what is going to happen when they found out who their daughter/sister has been dating? Is it going to be a Fairytale or is it going to be a Royal disaster?
