Pop star Psy fears alcohol is ruining his Gangnam Style.

The South Korean pop sensation behind last year's (12) most catchy tune admits vodka has become his "best friend" and "vice partner," and he reveals he drinks whisky and tequila to lift his spirits.

He tells Britain's The Sunday Times newspaper, "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."

The entertainer explains the only time he doesn't consume alcohol is when he is hungover, which he claims is a lot.
