American singer-songwriter Sheryl Crow says she has been diagnosed with a benign brain tumor after forgetting the lyrics to some of her hits while performing. \"I worried about my memory so much that I went and got an MRI. And I found out I have a brain tumor,\" Crow, 50, told the Las Vegas Review-Journal. \"And I was, like: \'See? I knew there was something wrong,\'\" she said. \"I haven\'t really talked about it. In November, I found out I have a brain tumor. But it\'s benign, so I don\'t have to worry about it. But it gives me a fit.\" The newspaper said Crow\'s condition doesn\'t seem to be slowing her down. She is working on a new album, as well as writing a stage musical version of \"Diner\" with Barry Levinson, the writer-director of the 1982 film.
