The twins from "Full House"— Ashley and Mary-Kate Olsen, have settled a long-running legal feud with former interns and have agreed to pay up to $140,000, E! Online reported. The class-action suit against the multi-billionnaire actor turned fashion designers, was filed in 2015, when about 40 present and past interns for Dualstar Entertainment Group, alleged that they were either unpaid or paid less than the minimum wage after working extended hours.

Since then, about 180 present and past interns have to be cleared off their arrears.

The payout will come to about $530 per intern, who apparently toiled for up to 50 hours a week for months for Olsen sisters, who run a business empire worth about $300 million, according to E! Online.

Shahista Lalani, the former design intern was the lead plaintiff in the case. She blamed the Dualstar Entertainment Group, which released the Olsens' 2004 film "New York Minute" and also provides their fashion apparel, for treating her poorly and making her work for free in 2012.

Talking about head technical designer for the Olsens’ fashion label, The Row, Lalani said: “She was very demanding." "I was doing the work of three interns. I was talking to her all day, all night. Emails at nighttime for the next day, like 10 p.m. at night," she had said, Page Six reported in August 2015. “The head technical designer was like, ‘Go get my Advil. I need this and this because I’m feeling sick and I have this meeting.’

Lalani even said that the work pressure took a toll on her health and she had to be hospitalized for dehydration.

Although, Lalani never worked directly for the Olsens, but said she saw them occasionally at meetings and liked them. “They’re really nice people,” she had said. “They were never mean to anyone. They’re business people.”

The interns were from Parsons School of Design in Manhattan and worked under the head technical designer for the Olsens’ fashion label, The Row, for five months.

In response to the allegations, Dualstar representative Annett Wolf wrote in a statement to USA Today in August 2015: "As an initial matter, Dualstar is an organization that is committed to treating all individuals fairly and in accordance with all applicable laws." "The allegations in the complaint filed against Dualstar are groundless, and Dualstar will vigorously defend itself against plaintiff's claims in court, not before the media. Dualstar is confident that once the true facts of this case are revealed, the lawsuit will be dismissed in its entirety," she had said.
