MANILA, Philippines - She's 50 and in great shape.

Perhaps because, aside from being a health buff, Madonna doesn't smoke.

And so when the queen of pop got a wiff of second-hand smoke from some fans during a rainy concert in Santiago, Chile, on December 19, she threatened to cancel her show.

Here are some lines from Madge captured by TMZ.com from one of the many videos of the incident now posted on YouTube:

"There are people smoking right now. No smoking!

"If you're going to smoke cigarettes, I'm not doing a show.

"You don't care about me? I don't care about you. All right?

"Are we going to play that game? I'm not kidding. I can't sing if you smoke... Entiendes?

"You're looking right at me and smoking cigarettes, like I'm a stupid f**king idiot."

Watch this video. You can hear non-smoking fans cheering Madonna on for her sass:

After the brief blow-up, Madonna's concert continued. According to TMZ, the smoking fans were forced to extinguish their cigarettes.
