Britney Spears allegedly ‘amped’ on caffeine: ‘Keep knives away from her’

Britney Spears is amped up on caffeine, according to a new documentary — and apparently, it’s not surprising.

TMZ is producing a Spears doc that will air Monday, and sources with “direct knowledge” claimed to the outlet that the 41-year-old singer guzzles caffeine by the gallon — consuming so much that sometimes she stays awake for three consecutive days.

Spears reportedly drinks Red Bull, Celsius, coffee and dandelion tea “almost nonstop.”

Experts — including media personality and addiction medicine specialist Dr. Drew Pinsky — told TMZ that those who suffer from mental illness often crave the high they get from caffeine, though it’s not healthy or great for them.

“TMZ Investigates: Britney Spears: The Price of Freedom” takes a look at the “Baby One More Time” singer’s life since her conservatorship ended a year and a half ago.

After her public meltdown in 2007, Spears was first put into conservatorship in 2008 by her now-estranged father Jamie Spears, which lasted until it was lifted in November 2021.

The TV special touches on her relationships with her family and kids, her marriage to Sam Ashgari, a failed intervention and concerns that those closest to her have observed.

Spears married Kevin Federline, 44, in 2004, and had a son, Sean Preston, now 17, then another, Jayden James, now 16. She divorced Federline two months after Jayden was born in 2007.

Her relationship with her sons has been fraught since she entered a 13-year-long conservatorship in February 2008 and went through a custody battle, during which the couple shared their sons 50/50.

Sean and Jayden were noticeably absent from Spears’ wedding to Asghari, 29, which Federline alleged was because they had chosen not to see her.

“Britney Spears has had a year and a half of freedom since the conservatorship ended, but there are big problems,” narrator and TMZ Executive Producer Harvey Levin said at the beginning of the explosive trailer for the doc.

The trailer even has TMZ’s managing editor Fabian Garcia claiming that Spears “got physical with Sam,” and Levin claiming her marriage is in “deep trouble.”

The hour-long doc also uncovers some of the advice those taking care of Spears made as the conservatorship — including to “keep knives away from her.”

The “Toxic” singer has been the subject of quite a few recent documentaries surrounding her conservatorship and the #FreeBritney movement — though she had no involvement in any of them. 

“With 4 documentaries released about me last year with people I adore speaking about my past !!” she wrote in a previously deleted Instagram post. “Unfortunately, the way my past was portrayed in those documentaries was extremely embarrassing !!! It felt semi-illegal !!!”

Spears is also in the midst of working on an explosive autobiography — but it’s reportedly been delayed over concerns among the A-listers mentioned in the book.

Simon & Schuster has put the memoir, which was originally expected to be released this past February, on hold after receiving letters from two of Spears’ famous exes, according to the Sun.

“Britney is brutally honest in the book — there are a lot of nervous A-listers,” a source told the outlet. “Strongly worded legal letters have been sent to the publishers by people who know Britney and who fear what she has written. There is no movement at the moment, and there are concerns over when it will eventually be able to come out.”

“TMZ Investigates: Britney Spears: The Price of Freedom” airs Monday, May 15 at 9 p.m. ET on Fox. It will also be available on Hulu and Fox Entertainment’s streaming platform, Tubi.
