Sheryl Crow took to the stage at the 66th annual Tony Awards at the Beacon Theatre in New York Sunday night -- it was her first public appearance since her stunning revelation that she has a benign brain tumor.

Crow -- looking radiant in a navy-blue floor-length gown -- took to the stage to present the award for Best Original Score.

After host Neil Patrick Harris gave her a singing introduction, Crow, 50, quipped that she'd work it into her theatrical score for the musical version of Barry Levinson's movie Diner.

As Breaking Celebrity News has previously reported, Crow recently revealed to the Las Vegas Review Journal that she has a benign brain tumor.

"I worried about my memory so much that I went and got an MRI. And I found out I have a brain tumor," Crow said. "I haven't really talked about it," she continued. "In November, I found out I have a brain tumor. But it's benign, so I don't have to worry about it."
