"The names we are still talking about, and I've just been told that he was born on Elvis's birthday - then one of them we'll call Elvis so far," Crown Prince Frederik joked (?), The Sydney Morning Herald reports.
It's reported that the Prince drove his wife to the hospital earlier in Saab. The couple has two other children: Christian, 5, and Isabella, 3.
Crown Princess Mary is 38 and was born in Tasmania. The newborn twins are expected to the leave the hospital this week and go home to Amalienborg Palace. The names might not be announced for another two or three months, when the babies will be christened.
Unless Prince Frederik wasn't joking about Elvis.
