Prince Harry and Rihanna have taken HIV tests together to mark World Aids Day.
The pair sat side by side at the Man Aware event in Bridgetown, Barbados.
The British royal and the Work singer took the same test, which is a simple finger prick which produces results in 20 minutes.
Both Rihanna and the prince tested negative.
It was the second time that Harry had taken a public test in five months in an attempt to reduce the stigma surrounding the virus.
The prince had teased Rihanna that the test would be painful and winced as the needle went into his finger.
Rihanna however, proved that she was tougher than the prince, saying: “You made it seem like it hurts.
“It’s not as painful as you said this morning.”

The prince had met Rihanna early that same day where he looked delighted to be introduced to the global superstar – he had no idea she was attending.
The Queen’s grandson read a message from the monarch where she paid tribute to Barbados and its people who, since achieving independence from the UK on November 30 1966, “have continued to flourish and grow into a strong and confident nation”.
Rihanna wore a long dress – a demure fashion choice compared to her pop videos which feature risque outfits – while the prince, who is on a 15-day tour of the Caribbean, looked smart in a suit, shirt and tie.
The prince read the Queen’s message to the guests: “Prince Philip and I send our warmest wishes to the Government and the people of Barbados on the occasion of your 50th Anniversary of Independence.
“Since you became an independent country in 1966, you have continued to flourish and grow into a strong and confident nation.
“The extraordinary talents of your people, from the cricket field to the music industry have been admired and recognised throughout the world. Barbados remains a favoured holiday destination for British people, not only for the incredible natural beauty of your country but because you have a great warmth and generosity of spirit.
“Over the years I have visited Barbados five times and you have kindly welcomed many other members of my family.
“Our countries have a shared history, shared values and an affection which continues to bind us in friendship. On this day of celebration, I send my congratulations to you on your Golden Jubilee of Independence.”
Before asking guests to raise a glass to Barbados, prime minister Freundel Stuart feted Rihanna and the other star guest Sir Garfield, in a speech.
From a rostrum outside, Stuart told guests seated in the marquee, he was pleased Harry was there representing the Queen.
He said: “Especially welcome too is the Barbadian superstar Rihanna, whose presence here this evening lends a perfect enhancement to the occasion. We are very pleased to have her here.”
