Sheryl Crow is suffering from a brain tumor. The Grammy winner and breast-cancer survivor has a common form of brain tumor called a meningioma.

The 50-year-old singer broke the news to a reporter on Monday.

"I worried about my memory so much that I went and got an MRI. And I found out I have a brain tumor. And I was, like, 'See? I knew there was something wrong.' I haven't really talked about it...But it's benign, so I don't have to worry about it. But it gives me a fit," she told Las Vegas Review-Journal columnist Doug Elfman.

She felt concerned when she forgot the lyrics to "Soak Up the Sun" on stage in February and joked to the Florida audience that her brain had failed: "I'm 50, what can I say? My brain's gone to s**t."

"Half of us are walking around with [meningioma] but you don't really know unless you happen to have an MRI. [Sheryl] has no symptoms and everything is fine. It was a random mention during the interview. It was not meant to alarm anyone. She is doing great and is healthy and happy," her representative told E! News.
