The pop star joined DJ Spade’s Instagram Live session on Saturday night and joked about Durant having coronavirus, wondering whether she should wear a mask in the chat, before wishing the former Golden State Warriors a speedy recovery.

Earlier this month, four Brooklyn Nets players tested positive for COVID-19. While the team did not identify the quartet, Durant told The Athletic he was one of the four and confirmed he had contracted coronavirus.

The two-time NBA champion’s reply was typically swift, as he addressed Rihanna as “Robyn”—the pop star’s actual first name—and wondered whether she’d just returned from Europe, which has been ravaged by the pandemic over the last month.

“Is KD allowed in here?” Rihanna asked. “Should I wear a mask to live?” She then wrote, “But foreal get well soon KD.”

Durant acknowledged his cough sounded “Rona-ish” but warned Rihanna she could have picked up the virus in Europe without showing any symptoms, as the virus was “lurking” across the Atlantic since December.

“Yo Robyn didn’t u just come from Europe?”

The nine-time Grammy Award winner, however, replied saying she had been back in the U.S. for at least two months.

Drake also chimed in with a joke, but was swiftly ignored by Durant.

Durant is one of 13 players or team members in the NBA to have tested positive for coronavirus, since Utah Jazz center Rudy Gobert became the first player to test positive for COVID-19 on March 11.

Gobert’s teammate Donovan Mitchell and Detroit Pistons forward Christian Wood also have tested positive.

Two weeks ago, the Philadelphia 76ers and the Denver Nuggets both announced members of their organizations had tested positive to COVID-19, but neither team confirmed whether any of their players were affected.

On the same day, two Los Angeles Lakers players and Boston Celtics guard Marcus Smart were also confirmed to have tested positive for the virus.

The latter, however, announced on Sunday night he had completely recovered.

As of Monday morning, over 143,000 cases of coronavirus have been reported in the U.S.—the highest tally in the world.

Over 2,500 deaths have been recorded in the country and almost 5,000 people have recovered, according to Johns Hopkins University, which has been tracking the outbreak using combined data sources.

Over 34,000 people have died globally since the outbreak of coronavirus began in Wuhan, a city located in China’s central Hubei province, late last year. There are over 724,000 cases globally, with more than 152,000 recovered.
