• Britney Spears drinks coffee and energy drinks "by the gallons" so she can stay awake for days, according to a new documentary.
• The TMZ documentary, "Britney Spears: The Price of Freedom," aired Monday on FOX.

Britney Spears keeps herself so over-caffeinated with energy drinks and coffee that she stays awake for up to three days at a time, and has a "constant fear" that she will be placed back under a conservatorship, according to a new documentary from TMZ.

"Britney Spears: The Price of Freedom" premiered on FOX and streaming service Hulu on Monday evening, and features many of TMZ's own executives and producers as talking heads.

The documentary focuses on the singer's life after she was released from her 13-year conservatorship in November 2021, but has also drawn criticism from fans for not including any firsthand accounts from those that know Spears, 41, personally.

At one point in the documentary, TMZ executive producer Harvey Levin claimed that "multiple sources" close to the "Hold Me Closer" singer had told him that she "drinks coffee, Red Bull, Celsius, and dandelion tea by the gallons and that contributes to her manic episodes."

He added: "We're told that she sometimes stays awake for three days at a time."

Celebrity addiction specialist Dr. Drew Pinsky weighed in, adding that people with mental illnesses "gravitate" towards such stimulants to keep their energy up.

Elsewhere in the documentary, TMZ's news director Brad Appleton echoed Levin's words, claiming that Spears is a "binge sleeper" who sleeps for several consecutive days and then "won't sleep at all for the next few."

Levin also claimed that the "Toxic" singer, who was placed in a court-ordered conservatorship for more than a decade following a series of personal issues in 2008, has a "constant fear" of being re-institutionalized.

He said that Spears "lives in mortal fear" that "someone will come in the middle of the night, strap her to a gurney and take her to a psych ward."

When she's not posting on social media, the mother-of-two "lives in virtual isolation," further claimed TMZ executive producer Charles Latibeaudiere.

Spears' representatives did not immediately respond to a request for comment.

The star's husband, Sam Asghari, made his feelings about the documentary clear in an Instagram Story, which has since been deleted.

Ahead of the documentary's release on Monday, the American-Iranian model criticized TMZ for putting Spears "under a microscope" and telling "her story" without her approval.

Asghari also told fans of the singer to not "believe what you read online," describing the actions of those involved in the production of the 45-minute documentary as "disgusting."

"99% of the time those are all clickbait for you to click and for them to make money, and that time is over," he added.

Asghari wed the pop star in 2022 in a ceremony that was not attended by any of her close family, including her teenage sons Sean, 17, and Jayden, 16, whom she shares with ex-husband Kevin Federline or her parents, Lynne and Jamie Spears.
