Reese Witherspoon's daughter Ava Phillippe dazzled at Saturday's 25th annual Bal des Debutantes in Paris

It was an evening ripped straight from the big screen.

Reese Witherspoon and Ryan Phillippe‘s daughter Ava Phillippe dazzled at Saturday’s 25th annual Bal des Debutantes in Paris, where she was one of 20 young women being introduced to society at the famed event.

The look-alike to her Oscar-winning mom, 18, showed off her gold ballgown by Giambattista Valli Haute Couture as she entered with her escort, Maharaja Padmanabh Singh of Jaipur. The duo then took to the dance floor for the first waltz, where Phillippe twirled to a song from hit film La La Land as other debutantes watched on.

A polo playing acquaintance of Prince William, Phillippe’s date Singh’s presence at Le Bal has attracted press attention in Paris. Known to friends as “Pacho,” he’s a member of India’s national polo team — who told journalists he’d only asked friends to show him the steps for the waltz (the ball’s traditional opening dance) in the past few weeks. His sister, the Princess Gauravi Kumari of Jaipur, also made her debut this season.

Lori Harvey, the daughter of TV host Steve Harvey, was also among the six American debutantes. She wore a black Elie Saab dress with a plunging neckline and feather details.

The Hollywood offspring follow in the footsteps of previous celebrity children including Robert Kennedy Jr.’s daughter, Kyra Kennedy, Larry David’s daughter, Romy David, Sylvester Stallone‘s daughter Sophia Rose Stallone as well as Bruce Willis and Demi Moore‘s daughters Scout and Tallulah Willis.

Launched in 1992 by Ophélie Renouard, the debutante ball invites young women from around the world who come from notable families.

Leading up to the debutante presentation at the Peninsula Hotel, both the Harvey and Witherspoon families celebrated Thanksgiving in Paris — going shopping, visiting museums and taking in the local sights in the City of Light.

On Friday, Phillippe and her mother attended the Bal des Debutantes’ traditional “day before” breakfast and run-through, with the teen trying her designer gown while Harvey, 20, practiced walking around in her dress — telling Madame Figaro, her nightmare “was probably falling.”
