Diana Ross for Glasto?

Diana Ross has got music fans excited with talk she may be appearing at next year's Glastonbury Festival.

The annual event is one of the highlights of the music calendar year, and last year fellow singing legend Dolly Parton wowed festivalgoers with her set.

Now Glasto bosses are said to have their sights firmly set on Motown hero Diana.

"[They] were thinking it was going to be impossible to top Dolly. But now it looks like they will get Diana Ross, which will be incredible," an insider revealed to British newspaper The Sun.

"It won't be cheap but she's worth every penny. She still tours around the world and puts on a fantastic show."

If Diana gives the green light, she'll be following in the footsteps of Shirley Bassey, Johnny Cash and Kenny Rogers who have all mixed their classic sound with more contemporary artists at the festival.

One person who's backing the 70-year-old superstar is close friend Nile Rodgers from disco band Chic.

"Diana is one of my greatest friends and she is an incredible performer. I know she'd love to feel the vibe and the love from any festival audience," he gushed, before admitting she's still as demanding as ever.

"Sure, she's a diva. But I absolutely love divas because they care and are passionate about what they do.

"I once saw her being told she was singing flat and she stormed out of the studio and went to France for two weeks — she says she doesn't remember that happening," he laughed. .
