United Kingdom, April 21 -- Billy Idol has gone teetotal.

The 69-year-old 'White Wedding' rocker used to enjoy a few glasses of wine with his dinner, but he's now given up booze completely because he's "watching out" for his liver and can't stand suffering hangovers any more.

He told The Independent newspaper: "I've actually just stopped drinking. I used to have a glass of wine at a restaurant.

"I'm just watching out for my liver these days - unfortunately! I'd love to be piling them back! Then again, you put on weight, that's all that happens with alcohol these days. You just get puffy ... [Plus] I started getting a really bad headache if I have more than two glasses of wine."

Billy previously battled drug addiction back in the 1980s...
