The sneak peak shows Hilton opening up about the mental abuse she endured at boarding school in Utah, as a child.
"I'm nervous. I'm shaking. It's hard to even eat, because my stomach is just like, turning. I don't know—it's something that's very personal, and not something I like talking about. No one really knows who I am."
The synopsis of This Is Paris details how the film sets to uncover "the hidden past of the international icon.”
“As Paris confronts the heartbreaking trauma that forged who she is today, this deeply compelling portrait tells the real story of a teenage girl desperate to escape into a fantasy and sheds new light on the Insta-fame culture that Paris helped to create.”
Despite the emotional content, during an appearance on The Talk, Hilton described filming as "very therapeutic" and said the end result will allow fans to "see a different side to me than they've ever seen before."
She added, "Because I honestly didn't even know who I was up until this year. I really learned a lot about myself through this film."
This Is Paris is set to air on September 14 on YouTube.
