Inside Hailee Steinfeld's Sweet Sixteen


Oscar-nominated actress Hailee Steinfeld recently celebrated her sweet 16 with pals like Victoria Justice and Willow Smith, and ET is taking you inside the fun-filled Sally Hansen and vitaminwater-sponsored bash.

"It's my sweet 16, I'm so excited -- I'm so happy," a giddy Hailee said. "You know, to be honest, I've been away from home for a long time, so to just have all my friends and family here together in one night is all I could ask for."

The always fashionable star -- who was the face of Miu Miu at just 14 years old -- was clad in a checkered Louis Vuitton romper and ankle-strap heels on her big night, which was attended by the who's who of young Hollywood including Lucy Hale, Willow and Jaden Smith and Twilight's Booboo Stewart and MacKenzie Foy.

Inside the big party, which included vitaminwater mocktails and manicures, Victoria revealed her previously unknown shared modeling past with the birthday girl.

"We actually modeled together for a Guess shoot when we were like, really little," she smiled. "So I'm really happy for her. This is a huge milestone ... I think she's awesome and really talented."
