Angelina Jolie and Brad Pitt’s Daughter Shiloh Choreographs Steamy Dance Performance Under the Name Shi at Hollywood Dinner for French Designer Isabel Marant

Angelina Jolie and Brad Pitt’s daughter Shiloh Jolie made an unexpected appearance at a dinner Thursday night in Los Angeles that celebrated the launch of French designer Isabel Marant’s capsule collection with Net-A-Porter.

But Shiloh wasn’t simply a guest at the fashionable soiree. Using the name Shi, she choreographed a sometimes steamy number by dancers Keoni Rose and Tako Suzuki that accompanied singer-songwriter Luella’s performance of her recently released single “Naïve.”

The dinner took place in the backyard of the Oliver House, a private residence designed by R.M. Schindler in the 1930s that overlooks the Silver Lake reservoir. Shiloh made a brief appearance at the cocktail hour before retreating into the home to hang with her dancers.

“It’s always a blessing for me to be here in Los Angeles, which I love,” Marant said. “It’s a city that’s really inspiring to me and resembles me.” She added that she feels “at home” in L.A. because of “all the cool girls with the Isabel Marant vibe.”

She then laughed, “We’re hungry,” before servers began streaming into the soiree with plates of cucumber salad followed by Pacific striped bass and coal-roasted beef loin entrees. Dessert featured pieces of tiramisu cut from a cake that was so enormous it needed to be carried out of the kitchen by two people.

Guests included former “Mad Men” co-stars Allison Brie and January Jones, Rachel Bilson, Lily Rabe, Shiloh Jolie, Stephanie Suganami, Madeline Brewer and models Dree Hemingway, Ever Anderson, Hilary Rhoda and Salem Mitchell. Milla Jovovich – who served as a co-host – attended with her look-a-like model daughter Anderson.

The dinner also marked the first Net-A-Porter event for its new CEO Heather Kaminetsky, who joined the company just five weeks ago. “Tonight, we’re celebrating an incredible collaboration, but really what we’re celebrating is a true creative force – Isabel Marant,” Kaminetsky said. “Isabel is the queen of Parisian style and a favorite among the Net-A-Porter customers. This collaboration and collection that she put together for us is timeless and easy to take for travel from the city streets top the beach and back again and everything in between. At Net-A-Porter we really try to creative memorable fashion moment just for the girl who’s confident and loves fashion and just likes to have a good time.”
