KT Tunstall has made a vow to never take drugs after seeing how fellow singer Amy Winehouse has been affected.

The Scottish solo artist claimed that she will never be tempted to take Class A drugs and insisted that seeing photos of the troubled 'Rehab' star on reported drug binges had reaffirmed her stance on the matter.

Tunstall admitted she wouldn't want to jeopardise her music career, saying: "Amy Winehouse is immensely talented and all I read is how much she drinks and who she's married to.

"I'm sure lots of people would love to see me on coke coming out of a club. But there's way too much at stake to muck it up just because I would get better known for being an idiot than for being a musician."
