Prince Carl Philip and Princess Sofia of Sweden welcomed a baby boy on Tuesday, according to the Swedish Royal Court.
The new prince, whose name has not yet been announced, was born at Danderyd hospital in Stockholm, measuring just over 19 inches (49 cm) and weighing almost eight pounds (3595 grams). Both mother and child are reportedly in good health.
The crown prince, who also holds the title of Duke of Värmland, and his wife, a former model, married in June 2015.
Prince Carl Philip, the only son of King Carl XVI Gustaf and Queen Silvia of Sweden, is currently fourth in the Swedish line of succession -- after his older sister, Crown Princess Victoria, his niece and goddaughter, Princess Estelle, and his nephew, Prince Oscar -- making his son fifth in line for the crown.
