Princess Charlene and Prince Albert II of Monaco are expecting twins.
The royal family will grow by two when the Princess, 36, gives birth at the end of this year, leading many to speculate which baby will inherit the principality.
The couple first announced in May that they were expecting.
According to the Constitution of the Principality, the first born baby is the closest in line to the throne, with priority given to males. What remains unclear is what will happen if the first born is a girl.
This is some kind of movie/anime plot unfolding. The one born a few seconds later is going to grow up bitter and angry that the "older" one inherits the kingdom and they'll end up becoming the villain
