Britney Spears has had a ROLLER COASTER of a career but has that career finally come to an end? Recently, Britney has been embroiled in legal battles between her mother, who wants conservatorship over her daughter, and her father who currently has strict conservatorship.

Spears has been in an out of rehabs and is reportedly not been taken her current medications. Her manager Larry Rudolph claims that the mix is just not working for her anymore. Her sister Jamie Lynn, has been staying with Britney in the hopes of keeping a eye out for any erratic behavior.

In an interview with TMZ, Britney Manager Larry Rudolph said he doesn't “want [Britney] to work again ’till she’s ready, physically, mentally and passionately. If that time never comes again, it will never come again. I have no desire or ability to make her work again. I am only here for her when she wants to work. And, if she ever does want to work again, I’m here to tell her if it’s a good idea or a bad idea.”

Spears’ new Las Vegas show “Britney: Domination” has been put on an indefinite hold with no other shows or performance scheduled in the near future.
