Pink revealed that she had coronavirus in tweets Friday night.

“Two weeks ago my three-year-old son, Jameson, and I were showing symptoms of COVID-19,” the singer wrote. “Fortunately, our primary care physician had access to tests and I tested positive.”

Pink sheltered in place for two weeks and tested negative a few days ago, according to her post. She encouraged people not to take the virus lightly.

“This illness is serious and real,” she wrote. “People need to know that the illness affects the young and old, healthy and unhealthy, rich and poor.”

n a follow-up tweet, Pink announced that she’d be donating $500,000 to Temple University’s Hospital Emergency Fund and another $500,000 to Los Angeles’ crisis fund.

More than 7,400 people have died from coronavirus in the United States, according to data compiled by Johns Hopkins. More than 275,000 people in the country have tested positive for the disease.
