Madonna Tells 10-Year-Old Daughter Lourdes to Wear Less Sexy Clothes

These days, the rules of Madonna's household are more along the lines of "like a virgin" than "express yourself." The pop icon is getting a taste of her own medicine — from her 10-year-old daughter Lourdes — and finding that with motherhood comes prudishness.

In a grand twist of irony, Madonna — who posed nude for her "Sex" book, simulated a sex act on a water bottle in her "Truth and Dare" movie, passionately embraced an African-American Jesus in her "Like a Prayer" video and kissed Britney Spears at the MTV Video Music Awards — is having to tell Lourdes not to dress so provocatively, The New York Post's Page Six reports.

"My daughter is going through a phase of wearing jeans so tight she can't bend her knees in them," Madonna told British Elle, according to Page Six. "I have a go at her and say, 'Can't you wear something else? You have a closet full of clothes and you wear the same pants every day. ...

"'And please wear a belt because I don't want to see your butt crack when you bend over.'"

Other reports surfaced recently that the mother of three — who's married to British director Guy Ritchie — won't allow Lourdes to date until she's 18.

The singer better hope her "lucky stars" will align when she tries to impose that rule.
