Concerned about her frequent memory lapses—including forgetting song lyrics onstage—Sheryl Crow got an MRI last fall and soon discovered she has a brain tumor, the Las Vegas Review-Journal reports.

“I haven’t really talked about it,” the 50-year-old mother of two tells the newspaper. “. . . But it’s benign, so I don’t have to worry about it. But it gives me a fit.”

A rep for Crow tells E! News the singer has a meningioma, a common form of brain tumor.

“Half of us are walking around with [meningioma], but you don’t really know unless you happen to have an MRI,” the rep tells the network. “[Crow] has no symptoms and everything is fine. It was a random mention during the [Vegas] interview. It was not meant to alarm anyone. She is doing great and is healthy and happy.”

Crow, who was diagnosed with early-stage breast cancer in 2006, tells the Review-Journal she forgot some of the words to her hit Soak Up the Sun during a concert last month.

The newspaper reports she told the crowd, “I’m 50, what can I say? My brain’s gone to [expletive].”

Thankfully, she’s still got her spirit.
