Trivia: In the opening scene where Mia is introduced and waves to the crowd from atop a staircase, (wearing a big red dress) she accidentally flings a bracelet off her wrist, where a footman catches it. That is the same footman who catches the snail Julia Roberts flings in Pretty Woman, and he uses the same line "It happens all the time".
Trivia: In the scene where Mia sees all of the past royals in her family the paintings on the walls, they are of writers and producers.

Answer: I have visited a lot of websites and they all say the movie is supposed to be taking place 5 years after the first one and that would put her at about 21 since it should be a little after her birthday. Don't assume because this movie's made 3 years after the first that that's how long after the first one it's meant to be set.
