Nile Rodgers thinks Diana Ross would be "wonderful" at Glastonbury.
The Chic star - who performed at the iconic festival in 2013 - hopes rumours the Motown legend will take to the stage at Worthy Farm, Somerset, South East England, this summer are true because she would put on a "special" show.
He said: "I have no advice for her, just go there and have a good time. She's amazing, we were chatting just a few days ago. If she does do it then it will be wonderful , it will be one of those great moments - like Dolly Parton or Chic when we played there - and it will be really unique and special."
And Nile would even like to join his pal on stage if his schedule allows it.
He added to BANG Showbiz: "If I happened to be in town at the same time then I'd possibly join her on stage. If it did happen then it would be mega!"
The 63-year-old singer also hinted Diana, 71, is planning to record new music.
He said: "I can't tell you what we were talking about.
"All I can say is that if she did do new music then it would be amazing.
"She's still great, her shows are phenomenal, I don't know if there are clips of her lately on YouTube, but she's still awesome and everyone that goes to see her tells me nothing but great stuff."
