LOS ANGELES — The Ecstasy made her do it.

Amy Fisher says she was strung out on the club drug when she shot her boyfriend’s wife in the face in 1992.

“I was using Ecstasy, a lot of Ecstasy,” Fisher, nicknamed the Long Island Lolita, tells “Entertainment Tonight” in an interview airing Thursday. “I had no control.”

Fisher was 16 when she visited the home of her much-older lover, Joey Buttafuoco, a car mechanic on New York’s Long Island, and shot his wife, Mary Jo, as she answered the door. The drug made her feel “stronger and confident,” she says.

“I just did something totally irrational,” Fisher says. “Believe me, rational people don’t go to do something like that in the middle of the day. It’s just insane.”

She served seven years in prison for the attack.

Buttafuoco pleaded guilty to one count of statutory rape and served four months in jail. His wife survived the shooting. The couple remained together after the Fisher affair but divorced after moving to California.
