Lady Gaga just says no to heroin, but Breaking Celebrity News has learned that when it comes to cocaine -- well, that's a different story.

The Poker Face singer (real name: Stefani Germanotta ) told Vanity Fair magazine, in a piece for its September issue, she's "terrified of heroin" but still does "mostly cocaine."

"I won't lie -- it's occasional. And when I say occasional, I mean maybe a couple of times a year."
