The palace said Mary has become the proud mother of "two fine children" at the national Rigshospitalet hospital in Copenhagen. "Both mother and children are doing well," the court said.

The boy, weighing 5 pounds, 14 ounces (2.7 kilograms) was the first one born Saturday morning, while his sister, weighing 5 pounds, 10 ounces (2.6 kilograms), was delivered 26 minutes later.

The 38-year-old princess was admitted to hospital early Saturday morning, accompanied by her husband Crown Prince Frederik, who was present during the whole labor.

"It's a miracle," the smiling father told Danish broadcaster TV2 and other media at the hospital. "It's two small hearts to keep an eye on."

Tasmanian-born Mary married the Danish prince in 2004. The couple already have two children, 5-year-old Christian and 3-year-old Isabella.
