Netflix unveils the full trailer for a brand new Britney Spears doco out next week

There is a brand new documentary coming to Netflix about Britney Spears and we can’t wait to watch it.

"I just want my life back" Britney can be heard in the opening scene of the trailer which was unveiled by the streaming service.

The new Britney vs Spears doco titled - which will hit Netflix on September 28 - will delve into her length conservatorship battle.

The Toxic singer was put under a conservatorship following her public breakdown in 2008, seeing control of her affairs be placed in the fans of her father Jamie Spears.

Filmmaker Erin Lee Carr has directed the Netflix docs, which has been in the works for years, following Britney’s ongoing legal battle.

The movie will also touch on the recent #FreeBritney movement.

Recently Britney’s attorney Mathew Rosengart has taken the next steps to have her conservatorship terminated "completely and inevitably" because it "'no longer serves a legitimate purpose", but reiterated that his biggest priority is the removal of the 39-year-old pop star's father as conservator of her estate.

The lawyer has asked Judge Brenda Penny to replace the patriarch with someone on a "temporary, short-term" basis from 29 September.

According to Variety, Mathew noted in the documents that Britney needs a prenuptial agreement after recently getting engaged to Sam Asghari, which would require the involvement of her conservator and argued that, because the Lucky singer's relationship with her father has broken down, his involvement would "impede the ability to negotiate and consummate a contract that all can agree is in Ms Spears’s best interests".

The attorney was responding to Jamie's motion on 7 September asking for the conservatorship to end entirely, and he confirmed Britney "fully consents" to it being dissolved as soon as possible, and he will file a motion to terminate it once her father is removed.

He also said Britney's other conservator, Jodi Montgomery, supports the termination, “subject to proper transition and asset protection.”

The lawyer has asked the court to set a hearing to discuss terminating the conservatorship "at its soonest convenience" and promised a termination plan would be in place at that point.

He also challenged Jamie's latest request from Britney's estate for the funding of more than $1 million in attorneys' fees, including $541,000 for "media matters", and said he would seek to have the conservator sit for a deposition on those issues, as well as seek an evidentiary hearing.

Jamie has previously denied wrongdoing in response to Mathew's allegations he has abused his position in control of his daughter's finances.

Britney vs Spears hits Netflix on September 28.
