The 16-year-old actress was also joined on the carpet by older sister Dani and BFF Zendaya.
Just a reminder that Bella will be in New York City TOMORROW (May 22) signing copies of her Seventeen cover at Barnes and Noble Union Square and hosting a screening of her new film. It all starts at 4PM, so get there early!
FYI: Bella wore a Zac Posen dress with Charlotte Olympia shoes, jewelry from Shay Jewelry , a vintage Movado watch, and EF Collection and Graziela Gems rings.
