Madonna's teenage son is "mortified" by her topless photoshoot, but the pop star's eldest daughter thinks the pictures are great.

The 56-year-old singer recently bared her upper body for Interview magazine, and 14-year-old Rocco, her son with ex-husband Guy Ritchie, is said to have been incredibly embarrassed by it.

"Rocco is mortified that his mum is still doing topless photo shoots,` femalefirst.co.uk quoted a source as saying.

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.

"Lola thinks it's rad (cool) 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,` the source added.
