She has struggled with addiction and gone through [experiences] that would kill an elephant. She is incredibly brave.” The Cabaret star has sought treatment for substance abuse in the past. “It’s no secret she has dealt with this for years,” her spokesperson Scott Gorenstein tells PEOPLE. “And when she felt the need to seek help again, she did.” Once she is out and ready for her next steps, Gorenstein says there are upcoming projects in the works, including a series of concerts later this year. Her latest song, “Until The End” with Wynton Marsalis, which was released on Dec. 2, was written and produced by Oscar-nominated composer and producer J. Ralph for the documentary Garnet’s Gold. As she puts it in the song: “It’s not over til the end.”
