With five music festival performances scheduled for 2021, 73-year-old rocker Stevie Nicks has decided to cancel them all, citing coronavirus fears and the surging Delta variant.

On Monday, the former Fleetwood Mac singer posted a short statement on Twitter announcing her decision.

"These are challenging times with challenging decisions that have to be made. I want everyone to be safe and healthy and the rising Covid cases should be of concern to all of us," she wrote. "While I'm vaccinated, at my age, I am still being extremely cautious and for that reason have decided to skip the 5 performances I had planned for 2021."

Nicks had been scheduled to perform at the Jazz Aspen Festival in Colorado and BottleRock Napa Valley over Labor Day Weekend, both weekends of the Austin City Limits Music Festival in early October, and the New Orleans Jazz and Heritage Festival.

Yet, most of the festivals themselves are continuing to move forward just with replacement headliners, like Chris Stapleton, who is filling Nicks' slot at the BottleRock concert.

"Because singing and performing have been my whole life, my primary goal is to keep healthy so I can continue singing for the next decade or longer," the statement concludes. "I'm devastated and I know the fans are disappointed, but we will look towards a brighter 2022."

Many artists have also canceled upcoming performances this week due to daily pandemic levels of coronavirus cases in the United States, including Lynyrd Skynyrd, the Counting Crows, and Michael Buble.
