Elon Musk and Erykah Badu both test positive and negative for COVID-19

Elon Musk and Erykah Badu may have COVID-19 ... or they may not. They're not really sure.

The ambiguity comes after Musk was tested for COVID-19 and received both positive and negative results. Separately, Badu was tested and received her results: positive in one nostril and negative in the other.

The SpaceX CEO said he was tested for the novel coronavirus four times in one day Friday and the results were split.

"Something extremely bogus is going on," Musk tweeted. "Two tests came back negative, two came back positive. Same machine, same test, same nurse. Rapid antigen test from BD."

Musk, who recently welcomed a son with singer Grimes, followed up the tweet by asking his followers who "know a lot about the PCR testing industry" about the rate of getting a false positive during testing.

Musk's tweet came before SpaceX pushed the launch of its second astronaut flight to Sunday because of high wind and weather conditions.

NASA Administrator Jim Bridenstine said anyone testing positive for COVID-19 must quarantine under NASA policy and remain isolated. Officials said contact tracing by SpaceX found no link between Musk and any personnel in close touch with the four astronauts, who remain cleared for flight.

Later that same day, Badu tweeted about her mixed COVID-19 results noting she was required to be tested prior to being on set.

"No symptoms. Was tested for COVID. Same machine. Left nostril positive . Right nostril negative. Maybe they need to call Swiss Beats so they can do a versus between them," Badu wrote alluding to Swizz Beatz and Timberland's popular Verzuz battles. "Funny thing is , Dr. ONLY reported the positive result. What the fack is goin on here. Rapid Test. $$$$ smh."

One of her followers pointed out to Badu that Musk had experienced the same thing.

"This is my third rapid test in 24 hours. SMH. It’s routine to take c19 test before a livestream broadcast for all band and crew," Badu wrote. "Earlier I took 2 and one was positive the other neg in separate nostrils ?? We need to investigate these tests further. I want my $ back."
