(CNN) Stevie Wonder will be taking a break from music.

The legendary singer-songwriter announced during a concert in London on Saturday that he will be undergoing kidney surgery.

"So what's gonna happen is this, I'm going to have surgery, I'm going to have a kidney transplant in September of this year. I'm all good, I'm all good, I'm all good. I have a donor, it's all good," Wonder said. "I want you to know I came here to give you my love and to thank you for your love. You ain't gotta hear no rumors about nothing, I told you what's up. I'm good. All right?"
