Welsh pop star Charlotte Church has vowed never to take illegal drugs because she's seen the devastating effects they have on her party-loving peers.

The CRAZY CHICK singer, who is famed for her partygirl lifestyle, insists she would never try cocaine or heroin because it is unsafe and unattractive.

Church says, "Yes, I like going out. But I draw the line at drugs. They just aren't my thing.

"I've seen so many people on drugs, sweating and gurning, and it just looks disgusting. I don't ever want to look like that.

"You just don't know what's in them - so how people can buy them off complete strangers I can't understand."
