Her directorial debut, Booksmart, is set to hit theaters nationwide in just over three weeks.
But Olivia Wilde stepped away from the film world on Wednesday night as she headed to the Billboard Music Awards in Las Vegas.
The 35-year-old actress-turned-director was joined on the red carpet by Beanie Feldstein and Kaitlyn Dever, the stars of her forthcoming movie.
Wilde glittered in a floor-length gold dress with a slit that showed off just a hint of her long legs.
She clamped a black belt with a large gold buckle around her waist, highlighting her slender frame.
The Drinking Buddies star added a couple inches to her 5ft 7in gold platform heels and looked to be going to be almost accessory free.
Her long blonde tresses were pulled back into an elegant bun, and she left a few locks free to frame her face.
