Sad birthday: Princess Ingrid Alexandra has to celebrate without Mette-Marit and Haakon. Crown Princess met her parents by telephone on her 20th birthday.

Instead of cake and presents, military drill awaited the second in line to the throne in Norway on her big birthday. “We sing the birthday song while the birthday child is doing push-ups, and it is important that we sing as slowly as possible so that the person has to do many laps,” soldier Frida Berge-Urgård says.
