This is Paris Hilton like you’ve never seen her before.

In the trailer for her upcoming YouTube Originals documentary, This Is Paris, the star pulls back the curtain on her glamorous life as she hints at painful childhood trauma.

“I feel like the whole world thinks they know me,” she says. “No one really knows who I am. … I don’t even know who I am sometimes. I didn’t used to be that way.”

“I’m so used to like, playing a character, that it’s hard for me be normal,” she adds.

This Is Paris premieres Sep. 14 on Hilton’s YouTube Channel.
