Sherri Papini‘s sharing her side of the alleged kidnapping that became national news and ultimately led to her sentencing on federal charges … claiming it really did happen, in a trailer for a new documentary.

Papini is speaking out for the first time in the upcoming documentary “Sherri Papini: Caught in the Lie” … shedding more light on her shocking 2016 disappearance and the subsequent aftermath.

In the trailer, released Thursday, Papini admits she kept secrets from the public … but, insists she really was kidnapped and tortured — despite the federal government claiming otherwise.

Papini claimed two Hispanic women kept her captive for weeks … hiding their faces from her via masks, chaining her to a wall and even branding her with the word “Exodus.”

DNA was found on Papini — both male and female — but, investigators initially found no matches. However, in 2022, James Reyes, one of her ex-boyfriends, claimed Papini stayed with him during her alleged abduction … and, DNA from Reyes was found on her clothes.

Papini was arrested in March 2022 … and, about six weeks later, she pled guilty to one count of making false statements and one count of mail fraud. She was sentenced to 18 months in prison, but served less than a year.

Sherri publicly admitted the whole kidnapping was a hoax at her sentencing hearing … but, it looks like she’s walking that completely back now — and, we’re sure there will be a whole lot more bombshells when the doc drops later this month.
