It doesn't look like Britney Spears will be returning to her Las Vegas residency anytime soon.

"As the person who guides her career, based on the information I and all of the professionals who work with her are being told on a need-to-know basis, from what I have gathered it's clear to me she should not be going back to do this Vegas residency, not in the near future and possibly never again," her manager Larry Rudolph told TMZ in an interview.

He admitted that Spears was almost done with rehearsals for the February launch when her father became sick. "It was the perfect storm. We had to pull her show because her meds stopped working and she was distraught over her dad's illness," he claimed.

Though Rudolph is not involved in her current legal troubles surrounding her conservatorship, he does reportedly have access to medical information that would potentially impact her career.

Rudolph said he lets Spears decide when and how she wants to work, if she does at all. He explained that last summer, when she wanted to tour, she called him "every day" out of excitement. Currently though, "she hasn't called me in months. Crickets. She clearly doesn't want to perform now."

Regarding the future, Rudolph said he wants her mental and physical states to be healthy and prepared. "I don't want her to work again 'til 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."
