In a shocking revelation, Oscar-winning British actress Helen Mirren admitted to GQ Magazine that she used to have a cocaine habit, even if it's just a little one.

"I loved coke. I never did a lot, just a little bit at parties," Mirren said.

So what made her quit? Learning that every time she snorted the powder, she's aiding Nazi war criminal Klaus Barbie, who was trafficking drugs, among other things, in South America during that time.

"... I saw how my little sniff of cocaine at a party had an absolute direct route [to Barbie]. And from that day I never touched cocaine again," Mirren said.
