Psy certainly knows how to get the party started -- but ending it is another story. In a candid new interview with the U.K.'s Sunday Times, the 35-year-old Korean pop star admits that he drinks all day and all night, regardless of whatever else he's doing or feeling.

"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. If it's hot, I'm drinking, if it's cold, I'm drinking," he shares. In fact, the only time he doesn't have a glass in hand, he reveals, is when he's hungover, which happens "a lot."

Psy's favorite libation is Korean vodka, which he calls his "best friend" and "vice partner," but he won't turn down other liquors. "Whisky, vodka, tequila, whatever," he says of his alcohol preferences.

The interview also delves into Psy's troubled past, which includes an abusive father and a stint in jail. (The "Gangnam Style" singer, who notched his three billionth view on YouTube earlier this month, was arrested in Korea in 2001 for possession of marijuana.)

Speaking about his run-in with the law, Psy describes it as a "horrible fail" but says it contributed to the person he is today. "As an artist, the more experience, the better the creation," he tells the Sunday Times. "I'm a very positive person. So if s--t happens, I think maybe this happens because a huge amount of happiness is coming to me."
