Pierre Casiraghi and Beatrice Borromeo's son Stefano makes rare appearance at medieval fight

Beatrice Borromeo and Pierre Casiraghi’s firstborn son Stefano made a rare public appearance during the "1st Meeting of the Grimaldi of Monaco Historic Sites." Grace Kelly’s great-grandson was on hand to support his father as he participated in a Béhourd fight. The young Monaco royal looked adorable for the outing sporting a baseball cap, white T-shirt and shorts. The 16-month-old was pictured keeping himself entertained by playing with one of his mom’s necklaces.

In addition to his wife and oldest son, Pierre, 30, also had the support of his mother Princess Caroline, cousin Louis Ducruet and uncle Prince Albert at the medieval fight. Beatrice and her mother-in-law could not hide their emotions as they watched Pierre fight — cheering him on, while also at times showing concern. The dad-of-two was dressed for combat with a sword and shield, while wearing armor and a viking helmet with chainmail aventail.

The Grimaldi Milites faced off against the Bécuts de Gascogne during the fight. The "Meeting of the Grimaldi of Monaco Historic Sites," which aims to combine the history of the Principality of Monaco and the Grimaldi dynasty, will be repeated every year during St. John's celebrations.

Beatrice, 32, showed off her post-baby body at the event on June 23 wearing an ivory summery blouse and khaki pants. Pierre and his wife of nearly three years welcomed their second child, a son named Francesco Carlo Albert in May

Like their firstborn, who was born in February of 2017 and named after Pierre's late father Stefano Casiraghi, the couple paid tribute to relatives with Francesco's full name. Both of the royals' sons share the middle name Carlo, which is a recurrent moniker in Beatrice's noble Italian family as well as the name of her father Don Carlo Ferdinando Borromeo. The newborn was also named after Pierre's maternal uncle Prince Albert.
