Britney Spears’ Netflix Documentary 'Britney vs Spears' Is 'Unauthorized': Report

Britney Spears didn't participate in Netflix's new documentary about her.

The pop princess doesn't acknowledge Netflix's "Britney vs Spears" documentary. The film, which will be released next week, follows the "Toxic" singer's 13-year conservatorship battle.

"This is another unauthorized documentary without her blessing or participation," an unnamed source told Page Six Wednesday.

Netflix released the trailer of the documentary Wednesday. "No one would talk. Until they did," a narrator says in the clip.

Filmmaker Erin Lee Carr spoke with the Los Angeles Times and said that she tried to contact Spears for the documentary. However, she never got a hold of her.

"I always hoped and dreamed and wished and prayed to the documentary gods. I tried to contact her repeatedly. But I had to sit with the understanding that it was unlikely ever to happen," she told the outlet.

When asked if Spears was aware of the film she created, Carr gave a positive response. "I sent her a letter and I have reason to believe that she was able to read it. I think she’s focusing on her new beau," she said.

The filmmaker also explained that many believed everyone in Spears' life just wanted to get their fives minutes of fame. Those she contacted didn't return her calls and some of those she really wanted to talk to didn't respond to her.

"I’ve made things without access before, but you need other people if you don’t have access to the main person. And Britney, at the time, had never spoken about the conservatorship," she continued.

The upcoming documentary is not the first non-fiction film to investigate Spears' circumstances. In February, The New York Times released the documentary "Framing Britney Spears" that premiered on Fx and Hulu.

The "Toxic" singer was reportedly embarrassed by the film and cried for two weeks after watching it. Carr said that her documentary is different and she wanted Spears to like it. She also admitted that she is a fan of Spears, so she brought investigative journalist Amy Herdy to fact check.

"She didn’t have my same level of bias because I was a fan," Carr said.

According to Carr, the film is a product of a two-and-a-half-year long investigative process about Spears' conservatorship. They wanted it to be a "definitive place" to understand everything about the matter.

"If you care about women, you should watch this movie. If you care about mental health, you should watch this movie. If you’re a fan of Britney Spears, you should watch this movie," she said.

"Britney vs Spears" will premiere on Netflix on Sept. 28.
