Paris Hilton is ready to show her fans a whole new side of herself. The heiress gets candid about her “hidden past” in the upcoming YouTube Originals documentary “This Is Paris.”

The doc promises to dive into the “heartbreaking trauma” that made Paris the businesswoman, model, DJ – and now, YouTuber – she is today, painting a “deeply compelling portrait” about a “teenage girl desperate to escape into a fantasy.” Paris’ sister Nicky Rothschild Hilton and mother Kathy Hilton will also make appearances.

Helmed by Emmy-winning director Alexandra Dean, the documentary was filmed over the course of a year… which Paris has called “very therapeutic.” “This Is Paris” premieres September 14th on Paris Hilton’s YouTube channel.
