Clash of the Titans: Even diehard Madonna fans may have missed the Queen Of Pop’s catfight with the Queen Of Motown – Diana Ross herself

Both women grew up in the Detroit area, Madonna in the suburbs of Pontiac and Rochester Hills and Diana in the city, also in the projects for several years.

As a child in the 1960s and 1970s, Madonna was captivated by the Motown music scene that emerged from Detroit and swept the world.

The reigning female star in the Motown orbit was Diana, as queen bee of the thunderously popular girl group The Supremes.

During an interview early in her career, Madonna cited Motown as an influence on her own work, adding, “Diana Ross was a big inspiration for me.”

In the 1990s, Madonna was a megastar, but it was Diana who was named the ‘most successful female artist of all time’ in the Guinness Book Of World Records.

When Diana appeared on TFI Friday in 1999, host Chris Evans brought up her Guinness award and joked, “I bet Madonna hates you, doesn’t she?”

“No, Iโ€ฆ” Diana said, bursting into laughter and confessing, “Maybe!” and added that she knew Madge personally.

Chris claimed Madonna was a “flash in the pan” next to Diana, who diplomatically objected: “No, she’s been there.” She has a pair of legs, yes?’

Four years later, Diana offered a more unfiltered โ€“ and rather more negative โ€“ view of Madonna from Graham Norton’s couch.

Graham asked if she was a “fan” of Madonna and, seeing Diana’s visible discomfort and long silence, giggled: “I don’t feel so.”

โ€œWell, my kids went up to her and asked her for an autograph, and she wasn’t nice,โ€ Diana said. ‘And I won’t forget it. So that’s it. That’s what I think about it.’

Diana, who has herself been accused of formidable diva behavior over the years, said Madonna “wasn’t nice” to Diana’s children “and I’m nice to everyone, you know, and I just feel like she could have been.” . nice, but she wasn’t.’

About a decade later, however, Madonna seemed to take a warmly nostalgic view of her earlier encounters with Diana.

In 2015, she posted a throwback photo of herself in the early 1980s with Diana, Nile Rogers and Madonna’s then-boyfriend John ‘Jellybean’ Benitez.

‘Nile Rodgers, Diana Ross, Jellybean and I are wearing a Keith Haring skirt. Painted for me! It doesn’t get much better!!’ Madonna wrote with a heart emoji.
