Music icon Stevie Wonder has told fans at his Hyde Park show in central London that he will undergo a kidney transplant later this year.
Speaking to the crowd at his headline slot at the annual BST Hyde Park event, he said he will perform three more shows before taking a break ahead of the procedure planned for September.
Wonder told the crowd: “I’m all good, I’m all good, all good, I have a donor and it’s all good.”
He added: “I want you to know, I came here to give you my love and thank you for your love.
“I love you and God bless you.”
He said he wanted to tell his fans first, before rumours about his health started.
After his announcement, he performed his closing song – the chart-topping Superstition.
His fans cheered and clapped for the star and gave him a raucous applause as he was led off the stage.
The 69-year-old American performed some of the biggest hits of the 20th century, including Signed, Sealed, Delivered and Master Blaster.
He took time between tracks to thanks his fans for the support they had given him over the years.
He was supported by Lionel Richie, who in the past has cited Wonder as his inspiration for getting into the music business.
The BST Hyde Park concert series began on Friday with a show featuring Canadian star Celine Dion.
Barbra Streisand, Florence And The Machine and Robbie Williams will also take to the stage later in the week.
