Ava Phillippe, Reese Witherspoon's doppelganger daughter, is a Paris debutante

Reese Witherspoon's lookalike requires no introduction, but she got one anyway.

Ava Phillippe, 18, the Oscar winner's daughter with Ryan Phillippe, made her debut Saturday night at le Bal des Débutantes in Paris, where she was one of six young American women being introduced to society at the event.

The debutante wore a long-sleeve gold gown from Giambattista Valli Haute Couture and was escorted by Maharaja Padmanabh Singh of Jaipur, a polo-playing royal pal of Prince William's. The two waltzed in front of assembled media at The Peninsula Paris, which hosted the ball.

Mama Reese was on hand to support her mini-me, posting a day-after photo from Paris with Ava's 5-year-old brother, Tennessee Toth.

Steve Harvey's daughter Lori was also among the 20 debutantes.

Bruce Willis and Demi Moore's daughters Tallulah and Scout, and Carrie Fisher's daughter Billie Lourd, are other celebrity offspring who've made their debut at the exclusive ball created by French publicist Ophélie Renouard.
