The legendary American singer, 69, will take a break from music – and has found a donor for the operation which will take place in September.
Speaking on stage at British Summer Time Hyde Park with Barclaycard, he said: “I’m going to take a break. I’m going to have a kidney transplant in September. It’s all good. I’ve got a donor.
“It’s all good. I came here to give you my love. You ain’t go to hear no rumours about nothing, I’m telling you.”
Stevie made the announcement at the end of his set when he performed Superstition.
He said he would play three more shows before taking a break.
Stevie last played British Summer time in 2016, where he played iconic album, ‘Songs in the Key of Life’ in its entirety.
This time, he brought his fabulous Song Party show to the UK, which described as a “Celebration of Life, Love and Music”.
The career-spanning hits show saw the legendary singer perform some of this generation’s best known and much loved songs.
The Song Party tour has been playing a limited run in the US, and during one night, Wonder said: “We’re living in a time where there’s so much is going on in the world. But the one thing that we know for sure that we can celebrate is life, love and music.
“I’m very thankful that you all have been so wonderful to me, giving me your life and allowing me to share my music with you since I was 11 years old, which was just a little ago. So, we’re just going to play and have fun.”
