Reese Witherspoon and Ryan Phillippe's looks-like-her-mom daughter Ava Phillippe got the full princess treatment on Saturday, November 25 at the Bal des Debutantes in Paris (in some places called the Crillon Ball for being held at the Hotel Crillon, though this year it was at the Peninsula Paris), wearing a gold Giambattista Valli haute couture ball gown and dancing with an actual royal, her escort Maharaja Padmanabh Singh of Jaipur. And you thought being nominated for Prom Queen was impressive.

According to People, Singh (nicknamed "Pacho") plays Polo with Prince William and on India’s national polo team. In the past few weeks, he'd learned to waltz from friends, a skill that he showed off with Ava as they danced to a song from La La Land. (A fitting choice for a Hollywood girl.) And he's no stranger to the debutante circuit; "His sister, the Princess Gauravi Kumari of Jaipur, also made her debut this season," per People.

Since its inception in 1992, the charitable Le Bal has been something of a cross between a traditional debutante ball and a fashion show, with daughters from notable families around the world attending the event in couture, rather than the traditional white bridal-style gowns. Past debutantes of Le Bal include Lily Collins and Kyra Kennedy. This year, Ava Phillippe was one of six Americans present, including Lori Harvey (in a black Elie Saab dress), daughter of TV host and mogul Steve Harvey.

It's a good time to be in the Phillippe-Witherspoon family. Ava's living a fairytale and Reese, fresh off producing and starring in the Emmy-winning Big Little Lies, has a new show in the works with Jennifer Aniston that's already been given a 2-season order by Apple.
