Celebrities announcing that they are positive for the coronavirus or had the coronavirus has become routine today. But has there been an instance where one celebrity revealed another one’s positive diagnosis?

Page Six reports that Aubrey Plaza went on The Late Show With Stephen Colbert and revealed that COVID-19 infections happened during the shooting of her latest movie, Happiest Season.

When the Happiest Season was filmed in February, the global coronavirus pandemic was still something people saw as being confined in China. The actress then said that people started getting sick on set with what she believes is COVID-19, including Kristen Stewart.

E! Online says the 36-year-old Plaza clarified her statements immediately, adding that many people on the set of Happiest Season got sick. Plaza said none of the people in the film knew how pervasive COVID-19 would be since the disease only started gaining traction in the United States in March.

The actress says she only began to realize how serious COVID-19 would be after shooting the film and having a conversation with her driver to the airport. While asking whether she should be scared of the illness going around, the driver said that the disease was already in Pittsburgh.

While Stewart herself has not confirmed if she did have COVID-19, a positive diagnosis would make her just the latest Hollywood personality added to the list of celebrities that have shared their diagnosis.

One of the more recent Hollywood stars to reveal that they had the coronavirus is 27-year-old actor Ben Platt, who said he had the disease last March. Platt made the revelation over Twitter after a fan asked him if he knew anybody who had COVID-19.

Platt said that he had COVID-19 for three weeks and that he had already recovered from it. He also expressed his sympathy for people who have lost the battle with the disease as well as for those they had left behind.

Hugh Grant is also another celebrity that used The Late Show With Stephen Colbert as a platform to reveal his own COVID-19 diagnosis. The actor told Colbert that he could not smell anything when he had the disease and that he began sweating a lot because of it.

Other personalities that have contracted COVID-19 include singer and YouTuber Harvey Cantwell, Rita Wilson, Jim Parsons, Tom Hanks, Antonio Banderas, Bryan Cranston, Anna Camp, and Dwayne “The Rock” Johnson.

As of the Dec. 7 update from the Centers for Disease Control and Prevention, there are now 14,636,914 confirmed COVID-19 cases in the United States. The number of deaths is now at 281,253 people.
