5:12 PM PT -- Charles Harder, attorney for Tri Star Sports and Entertainment Group, tells TMZ ... "These claims are entirely false, as well as highly offensive, damaging and unacceptable."
Britney Spears is gearing up for a legal war with her former business managers at TriStar Entertainment -- a company heavily involved in her conservatorship, which she now outlandishly claims attempted to end her life.
The singer went off on TriStar Wednesday, especially its head honcho Lou Taylor and her righthand woman, Robin Greenhill -- 2 women who were allegedly an integral part of Britney’s life -- and she's accusing them of way more than just malfeasance.
Brit describes a meeting she says Greenhill and Taylor set up, and she claims Kate Beckinsale was also in attendance ... just to butter up Britney.
She says, "Ha those same bitches killed me a week later !!!! My dad worshipped those two women and would have done anything they asked of him !!!! I think they were trying to kill me … I still to this very day believe that’s EXACTLY what they were trying to do … but not a damn thing was wrong with me and I didn’t die !!!!"
She's never specific about HOW they allegedly tried to finish her, but Britney adds ... "Nobody else would have lived through what they did to me 🙅🏼♀️ !!! I lived through all of if and I remember all of it !!!! I will sue the shit out of Tri Star !!!! Psss they got away with all of it and I’m here to warn them every day of my precious life !!!!"
As we’ve told you, TriStar was hired by Britney’s father, Jamie Spears, early on in the conservatorship to handle her business affairs.
During her stay, we’d been told doctors worked on getting her the right combination of medications to get her stable -- but she looked totally out of it during a day out with her BF, Sam Asghari.
As for Taylor and Greenhill, we got the latter out at LAX last year and tried to get comment on claims that she’d been part of the team that greenlit the alleged bugging of Britney’s room once upon a time.
She didn’t say a thing though ... remaining mum on all things Britney.
Now, it sounds like Britney's at least considering getting some payback in court. We've reached out to Lou Taylor and TriStar, but no word back yet.
