London, July 25 (ANI): Britney Spears' self-arranged interview and photo shoot with OK! Magazine has been such a shocking disaster that it could ring the death knell for her career.

The singer had earlier personally called the magazine to ask bosses whether they would like to include an interview with her in their new issue.

She apparently not only wanted to set the record straight about her numerous problems including the feud with her mom, Lynne Spears, and her divorce with her estranged husband, Kevin Federline, but also her stint in rehab.

But insiders reveal to The Sun that instead, the singer only managed to dig a deeper hole for herself.

"Britney was in a shocking state," the paper quoted a source, as saying.

The insider reveals that Britney's bizarre behaviour included frequent toilet breaks, talking in baby talk and more shockingly vomiting all over her Gucci dress.

"She was babbling incoherently, talking in baby talk. She didn't make sense," the source said.

"Britney appeared to be out of her mind. She went to the toilet and when she came back she couldn't continue with the interview.

"Her eyes were rolling back, she was talking nonsense. She ate some food and vomited over her Gucci dress. She was a mess.

"She also seemed to be hallucinating, and kept saying strange and worrying things," the source added.

The insider also revealed that the pictures from the photoshoot are just as disturbing as they could 'kill her career'.

"The pictures are shocking and most of them are unusable. They paint a frightening picture and could kill her career. She looked like a young Courtney Love," the source said.

And while bosses at the mag were wondering whether or not to include the interview in the next issue, they have now decided to do so in order to tell 'the truth'.

Editor-in-Chief Sarah Ivens said: "OK! magazine spent a heartbreaking day with Britney Spears and witnessed first-hand an emotional cry for help that will leave you shocked and sad. This week, the truth will be told." (ANI)
