Madonna not happy Lourdes, 15, smokes

NEW YORK, April 19 (UPI) -- U.S. pop star Madonna admits she wasn't happy to see photos published showing her 15-year-old daughter, Lourdes Leon, smoking a cigarette.

"I wasn't very happy," the single mother of four told Harry Smith in an interview for TV's "Rock Center with Brian Williams."

"Honestly, I don't think I'm as tough as I should be [on my kids]. I think I need to be maybe tougher. It's hard -- every day is a negotiation," she said. "But cigarette smoking I'm not very fond of for anyone. I don't approve of anyone smoking cigarettes -- most of all my daughter."

Smith then noted Madonna smokes in her new "Girl Gone Wild" music video.

"I don't smoke," she said. "That's just an accessory, Harry. There's a difference. [Lourdes] smoked that cigarette before I did that video."
