Queen Mary of Denmark has revealed her eldest son and heir to the Danish throne, Crown Prince Christian, is moving to Africa after graduating from high school.

The Royal House of Denmark announced last week that the future king, 18, will travel to East Africa for an “extended stay” until December.

Naturally, doting mom Mary — who shares four kids with King Frederik X — admitted that she will find it difficult not having her son around for the next few months.

“We are going to miss him unimaginably… very, very much,” she said while attending a ceremony in the capital city of Copenhagen on Wednesday.

The royal added that while she and Frederik are excited for him to embrace “deeper learning,” the pair “look forward” to hearing about his experience when he returns.
