However, the photos were given the seal of approval by Madonna's 18-year-old daughter Lourdes, who thinks the pictures of her mother - who also has adopted kids David and Mercy, both nine - are empowering.
The source told Heat magazine: "Lola thinks it's rad that her mom flaunts her stuff. She sees it as being all about feminism and celebrating strong women and the female form.
"She is trying to convince Madonna to come and speak at one of her college lectures, covering women's evolving image in pop culture.
"Lola couldn't be prouder and she tells Rocco to chill out."
