Britney Spears went "completely psycho" as she was rushed to L.A.'s Cedars-Sinai Medical center late last night, sources very close to the embattled singer, who has been designated a "special needs" patient, report.
"They had to strap her down to the gurney like a mental patient and she was going between laughing and hysterics," a hospital source tells Us Weekly, calling it "a total psychotic breakdown. She just went crazy."
Sources at the hospital are now reporting that Britney's meltdown had nothing to do with drugs or alcohol, as was originally believed. They say it's mental and that what went down last night was not unexpected.
Life & Style claims that Britney tested negative for drugs and booze. A source told the magazine, "Her blood test just came back, and, thank God, it was clean. There are no traces of drugs or alcohol of any kind."
Because Britney Spears is in Cedars-Sinai's special needs unit, staff are monitoring her around the clock. However, the source said when they got the call to monitor the singer, "none of us wanted to go sit with her." Shocking!
Britney Spears will be on lockdown for 72 hours.
LAPD Officer Jason Lee said Spears appeared to be under the influence of an unknown substance after she was taken to the hospital on a gurney following a bizarre, nearly three-hour custody standoff. No injuries were reported.
Once in the ambulance, paramedics could be seen trying to strap her legs down before taking off. Britney Spears was admitted to Cedars-Sinai and placed on a "medical hold" - essentially an extended mental evaluation.
Reports also say Britney Spears has not slept or eaten in days.
Says a Britney Spears pal: "She has good and bad days - it's mental instability. All she has is to think of something sad and she goes crazy."
Meanwhile, TMZ reports that K-Fed's lawyer, Mark Vincent Kaplan, will be in front of the court at 8:30 PST requesting Britney's visitation rights for Sean Preston and Jayden James (already limited) be revoked altogether.
