Beyonce and Jay-Z's daughter Blue Ivy has been named an honorary citizen of an Eastern European island - by officials who believe she was named after a local tree.

Bey and Hova did visited the island of Hvar last year, shortly after she announced her pregnancy, and a tree wrapped in oddly colored ivy is native to the island.

And now the mayor of the island's largest town has sent the couple a letter informing them, "The story of the origin of your girl’s name, Blue Ivy, has brought huge media attention and great tourism promotion to the town of Hvar. I have decided to grant your daughter the status of honorary citizen of the town.”
