Ruslana Korshunova — who featured in ads for Marc Jacobs, DKNY, Vera Wang and Nina Ricci perfume — was just 18 when she was a passenger on the since-deceased pedophile’s so-called Lolita Express on June 7, 2006, the Daily Mail first reported after the latest batch of documents were unsealed Thursday.

The trip to Epstein’s Little St. James was almost exactly two years before the Kazakh-Russian beauty signed to IMG leaped to her death from her ninth-floor balcony.

Her ex-boyfriend told The Post at the time that the model had problems that she kept “bottled up.”

Korshunova’s trip to Epstein’s island was just weeks before the moneyman was arrested in 2006 and later convicted of sex with underage girls.

He was listed as being with her on the flight, along with three of his staffers — bodyguard Igor Zinoviev, personal chef Lance Calloway and longtime assistant Sarah Kellen.

There was also a woman identified as Stephanie Tidwell — and an unidentified former UFC fighter.

It is unclear what happened when Korshunova arrived on the island, where Epstein was known to sexually exploit underage girls — sometimes with some big-name friends.

Several years after her tragic death, Epstein victim Virginia Giuffre’s attorney emailed her asking whether she knew Korshunova.

“I think it’s a long shot you would recognize her, but read the article I attached and then look at the pictures and see if you recognize her,” attorney Brad Edwards wrote in the newly unsealed 2011 email, attaching a link to a Newsweek report on the model’s death.

But Giuffre replied: “I am sorry to hear the news of Ruslana, and my condolences are with her family and friends.

“I can say that I have never had any meetings with her, sorry not to be of any help there.”

Korshunova died at the age of 20, after cutting a hole in construction mesh covering her ninth-floor balcony, squeezing through it and jumping.

“I heard what sounded like a gunshot or a bomb or an explosion,” said a stunned Con Ed worker talking to a cop nearby.

“I looked down the street, and I say to the cop, ‘Did that person just get hit by a car?’ ” said the worker, who identified himself only as Patrick, of Brooklyn.

The two men raced over. “Her arms were crushed,” Patrick said. “Her head was on the left side and blood was coming out in a pool.”

It was later revealed that Korshunova left long messages describing how she missed her home and family, and talked about problems with her love life.

She had also lost a lot of weight in the month prior to her death and had trouble balancing her personal life and her demanding work schedule, her ex-boyfriend told The Post at the time.

“I think she just gave up,” said Artem Perchenok, who was with the model on the last night of her short life.

He added that Korshunova kept her problems “bottled up.”
