The world has welcomed another royal baby!

Pierre Casiraghi and Beatrice Borromeo of Monaco had their first child — a son! — early on Tuesday, Feb. 28 at Princess Grace Hospital. The newborn’s name has not yet been revealed at this time.

The new royal baby is the great-grandson of the late Grace Kelly, Princess of Monaco and the grandson of Grace and the late Rainier III, Prince of Monaco‘s eldest daughter, Princess Caroline.

Caroline, 60, and her late, second ex-husband, Stefano Casiraghi, welcomed the baby’s 29-year-old father, Pierre — who is seventh in the line of Monaco’s royal succession — in September 1987. The couple, who were married from 1983 until Stefano’s death at age 30 in 1990, are also parents to kids Andrea Casiraghi, 32, and Charlotte Casiraghi, 30.
