"Paul Oakenfold: "Madonna was without doubt one of the best artists I have ever worked with. She had so many fantastic ideas and really took her music seriously. You can tell that with Madonna, everything is about the music. She's a global name but still works tirelessly in the studio, puts on her best possible live gigs and puts 100 per cent into everything she does. "She's really grounded too and easy to work with."

“Melanie Brown: "It's easy for critics to knock celebrities who choose to adopt, but it's a good thing that Madonna's doing. Not only is she highlighting the plight of orphans in Africa, she's also giving this little girl the chance of a better life." .”

“Kelly Ripa: "I think she's used to people gushing over her and all of that, but I think she quickly sort of came to realize that yes, in fact I do go to every concert. The last concert she did, we made eye contact. Okay, in my mind it was eye contact. Madonna has no recollection, but I know she stared at me. There's something about her. I think she's very clever and witty. She's really funny. She's really down to earth when she's here. And I just love that about her. And I love looking at her because she's a physical specimen. .”

“Gregory David Roberts: "She was so unfussy. I think the thing about Madonna is that she's tremendously intelligent. She's fiercely intelligent; she's very sharp, very funny, very witty, very quick and will not accept second best. She will pick you up immediately in a conversation and defend her position and will put it forward with a rigorous intelligence. I think it's intimidating to a lot of people - I love it! For me it can't get any better than that, so I loved that about her, but I do think a lot of people are intimidated by her and reading it as something that it's not. It's simply a fierce intelligence. She's one of the smartest people you could ever meet.”

“Miley Cyrus: "Madonna always reinvents herself, and that's what I want to do. Whatever comes my way that sounds good, that's what I want to do. Whether it's designing clothes or photography or whatever.”

“Peter Hook: "Madonna's like a Black Widow spider. She tends to use people, then they shrivel up and disappear. She sat there with her back to us, and Rob went up and said, 'We were wondering if you wanted to appear later at the club', and she just went, 'Fuck off.'”

“Sting: "She's outrageous, she's provocative, she's inscrutable. And over the years, we've all been witnessed to her evolution, from street smart kid sister to virgin bride, from sex goddess to a yogi. Her mind is as celebrated as her body, she's as feared as she's desired, she leads while others follow... A woman who is all woman, and all women." .”
