NY- A Brooklyn law student who shed her briefs for a Playboy TV series may have to kiss off her career after the sexy video made its way into e-mail in-boxes all over the city.

Adriana Dominguez – a third-year student at Brooklyn Law School – happily strips naked, gets spanked and holds gavels up to her bare breasts in the provocative clip.

“I wanted to do something a little crazy before I graduate and do become a lawyer … do something kind of out of character,” Dominguez said with a grin as she posed for photographer Andrew Einhorn inside his friend’s DUMBO apartment.

“Lawyers can be boring,” the 24-year-old later added.

But no one will ever call Dominguez buttoned-up.

The brainy blond with Ivy League credentials was looking for a lark last July when she answered a Craigslist ad for women to appear in the Playboy TV series “Naked Happy Girls.”

The episode, called “Rock Star and the Lawyer,” aired in January – and was barely noticed.

But in the past three weeks, a 45-second clip spread on the Internet among students and some faculty at almost every New York law school.

“I did not expect it to become so widespread,” Dominguez told the Daily News in an e-mail yesterday. “I do not know how it was leaked.”

The University of Pennsylvania graduate appeared embarrassed and anxious when The News spotted her coming out of a meeting with a top dean.

“We don’t want this to ruin the career of a young lawyer,” said law school spokeswoman Linda Harvey.

When she made the erotic video, Dominguez, a California native, seemed unfazed by the idea that it could wreck her future.

“I’m not that shy, so it wouldn’t bother me if, say, the opposing counsel has seen these pictures of me. I wouldn’t care,” she told Einhorn after he asked her if she had any concerns.

“When we shot, she knew what might happen down the road if these pictures might get shown to people in her field,” Einhorn told The News.

“But she had this self-confidence to not let that bother her. I don’t think that she felt that this would be negative in any way to her career,” he said.

The sexy stunt could have dire consequences for the would-be lawyer.

If she applies for the New York State Bar this year, Dominguez could face tough questions from the Committee on Character and Fitness, which examines the personal character of future lawyers.

“It may have an effect. It’s a possibility in the worst-case scenario that the person does not get admitted,” a committee representative said.

And potential employers are sure to discover Dominguez’s striptease with a quick Internet search.

Except for her naughty past, Dominguez has plenty to recommend her: she had a fall internship with the domestic violence unit of the Brooklyn district attorney’s office and served as treasurer of her law school’s Legal Association of Activist Women.

Her fellow students at Brooklyn Law, who have dubbed Dominguez “Porn Star,” said she should have been smart enough to know better.

“It’s a striptease. A bit trashy,” said one young woman on campus. “I look at her differently. She’s definitely smart. It was just a bad decision.”
