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.
In 2002, when Albert was still single, his father Prince Rainier quietly changed Monaco’s constitutional laws to allow his daughters, Caroline and Stephanie, and their children to inherit the throne should Albert fail to marry and produce an heir.
Charlene, a former Olympic swimmer from South Africa, married the Monegasque royal in July 2011.
In June, Prince Albert told The Associated Press that he and his wife were ‘overjoyed’, ‘thrilled’ and ‘very excited’ about the impending arrival of their child — or children, as it is now known, Daily Mail informs.
