Madonna's 17-year-old daughter Lourdes Leon was spotted on the beach in Cannes, France, sharing what appeared to be a joint with a couple of friends.

The daughter of the pop queen, who turns 18 in October, was seen passing the hand-rolled cigarette with her pals right out in the open, where pot is illegal, not to mention her being underage.

Two years ago Madonna publicly blasted her daughter after a photo of her, then 15, smoking a cigarette surfaced online.

During an interview ith Rock Center's Brian Williams, Madonna said, "I don't think I'm as tough (of a parent) as I should be. I think I need to be maybe tougher. It's hard though, it's hard, everyday is a negotiation. But cigarette smoking I'm not very fond of, for anyone. I don't approve of anyone smoking cigarettes - most of all my daughter."

While others report that it may just be a hand-rolled cigarette, it looks an awful lot like wacky-tobacky to us.
