Having already said how she wishes her daughter Lourdes would dress more conservatively, now it's emerged she has forbidden the youngster from dying her hair till she hits 14.
Lourdes made the revelation in a blog to promote her and Madonna's joint fashion line, aptly named 'Material Girl'.
"I’m 13 and I’ll be 14 in October, so I can’t wait for that because I am FINALLY allowed to dye my hair… THANK YOU MOTHER!!," says Lourdes, writing under her nickname of Lola, in an entry peppered with teen-speak, slang and capital letters.
She goes on to say: "I am totally obsessivo about 80's shorts… You know the kind that makes your butt look kinda big, with a grunge-looking shirt tucked in. It's kinda nerdy but I love it.
"And the 80’s are another huge obsession of mine, which is totally amazingly awesome because Material Girl…HELLO! It’s like 80's themed, which pretty much rocks, so yeah."
Lola goes on to say she loves London shopping, especially "the vintage stores down in Whitechapel, also a lot of hot guys hang there just in case y'all care".
And music wise, My Chemical Romance "is THE BEST BAND EVER for realzzzz. They are so awesome it hurts. If you don’t know who they are just… go away OR download their songs".
She signs off by telling readers: "Stay tuned if you don't already think I'm annoying."
Lourdes' fashion collaboration with her mum goes on sale at US store Macy's from August 3.
