Prince Philip and Princess Danica of Serbia have welcomed a newborn son, less than five months after their lavish wedding in Belgrade.
The royal couple released a series of family photographs today to mark the birth of baby Stefan last Sunday.
First-time parents Danica, 31, and Philip, 37, both looked delighted as they cradled their newborn after bringing him home from a Belgrade hospital.
Baby Stefan will be styled His Royal Highness Prince Stefan of Serbia, and is third in line to the throne.
His arrival comes just months after Philip and Danica tied the knot in front of a host of European royals at Belgrade Cathedral in October.
