Grace Kelly's children Prince Albert II and Princess Stéphanie stepped out for opening night of the Monte-Carlo International Circus Festival on Thursday, January 17. They were joined by Stéphanie's son Louis Ducruet and his lovely fiancée Marie Hoa Chevallier, each family member dressed in their monochromatic best as they celebrated the 43rd edition of the spectacle and enjoyed every performance. Stéphanie was particularly invested in the fun night as it seems she has indeed "joined the circus!" and been involved for quite some time.

The 53-year-old Countess of Polignac clearly inherited her Hollywood mom's love of entertainment, as she spearheads the acclaimed circus year after year. In fact, she organizes and oversees the entire event, right down to choosing the acts that will perform. Although, she doesn't just get her creativity from the late Princess Grace. Her father Prince Rainier was actually the one who started the festival!

Prince Rainier created the fantastical festival back in 1974. It has since become the largest and most prestigious circus event in the world. Now under Stéphanie's leadership (seen middle), it continues to feature the very best international acts around.
