Psy has confessed that he has a constant drinking habit.

The South Korean has become a worldwide star over the past year due to hit single 'Gangnam Style', but it seems he has taken to the bottle to cope.

Speaking to the Sunday Times, the singer said that alcohol often accompanies his different moods, revealing:

"If I'm happy, I'm drinking, if I'm sad, I'm drinking. If it's raining, I'm drinking, if it's sunny, I'm drinking."

When asked at what point does he stop imbibing booze, Psy replied: "When I'm hungover."

The 'Gentleman' star added that his tipple of choice is Korean vodka, but he also takes "whisky, vodka, tequila, whatever."
