Unlikely duo Rihanna and Prince Harry have joined forces in an attempt to raise awareness of HIV and AIDS.

The pair attended the Barbados National HIV/AIDS Commission’s Man Aware event today (December 1), located in the country's capital, Bridgetown, as part of World AIDS Day. There, the two took live HIV tests to try and destigmatize the disease as well as highlight the simplicity of getting tested.

Kensington Palace posted a video of the event to Twitter, showing Rihanna laughing off Prince Harry's low pain threshold, as he winced while getting his finger pricked.

"You made it seem like it hurts! It's not as painful as you said this morning," the "Work" singer noted, according to E! News, shortly after her own test was administered.

Both results came back negative within 20 minutes, effectively demonstrating the efficiency of getting tested for the virus.

Prince Harry -- who has worked to raise awareness surrounding HIV/AIDS over the past year -- was previously tested for the virus five months ago, which he shared with the public via a Facebook Live stream.

"It is amazing how quick it is,” he said, immediately following the same procedure back in July. "So whether you're a man, woman, gay, straight, black or white—even ginger—why wouldn't you come and have a test?"

The British royal also appeared onstage alongside Elton John at the 2016 International AIDS Conference in Durban, South Africa, days later, where he urged attendees to work toward de-stigmatizing the virus even further.

"It is time for us to step up to make sure no young person feels any shame in asking for an HIV test," he told the crowd via E! News. "It is time for us to step up to make sure that girls and boys with HIV aren't kept from playing with their friends, classmates, and neighbors. It is time for us to step up and acknowledge that stigma and discrimination still act as the greatest barrier to us defeating this disease once and for all."
