A Vanity Fair photo editor who was stuck with the $62,000 bill for a lavish trip to Marrakesh with fake German heiress Anna Sorokin testified at her fraud trial on Wednesday about how they became friends by visiting infared saunas in New York together. Rachel Deloache Williams, 31, became friends with Sorokin in 2016 when she was introducing herself as Anna Delvey, a German solar panel heiress. The pair became close and in May 2017, they went to Marrakesh on a lavish trip Delvey arranged and claimed she would pay for. When none of her credit cards worked as they tried to assuage Moroccan police and hotel staff during the trip, Williams was forced to pay the $62,000 balance they had racked up her credit card. It was more than she earned in a year at the time. She wrote about her experience with Sorokin for Vanity Fair last year in one of two articles about the case. On Wednesday, she retold much of that story but also gave new details about her friendship with the 28-year-old who has become known as the 'Soho gritter' and revealed that she has signed on to an HBO series about the story. Rachel Deloache Williams, 31, testifies against Anna Sorokin at her fraud trial in Manhattan on Wednesday Williams was at times embarrassed as she testified about her extravagant lifestyle with Sorokin and laughed when describing it to the jury They met, she said, in February 2016 and were friends for 18 months. At the start of their friendship, Delvey often paid for the pair to go to infared saunas in the East Village. They also dined together and worked out with celebrity trainer Kacy Duke with Sorokin footing the bill. Williams recalled her European friend telling her: 'You work harder for your money than I do' and being 'grateful'. They had dinner together at Le Coucou, the expensive restaurant in Sorokon's hotel - 11 Howard - but Williams never paid, she said. According to The New York Times, even she was 'embarrassed' on Wednesday as she described their extravagant trip to the jury. Anna Sorokin is shown as Williams leaves the stand, talking to her lawyer The 28-year-old Russian native is on trial for fraud. She is accused of duping bankers as well as Manhattan's elite Sorokin was dressed entirely in black on Wednesday in a shirt, skirt and tights. Her attorney has hired a courtroom stylist Williams became emotional at other points during her testimony on Wednesday The photo editor reached for tissues at one stage as she described her experience When they arrived, they checked in to a $7,000-a-night villa at La Mamounia, a five star resort. During one of their few days out, Sorokin spent $1,314 on linen dresses because she 'just had her New York black clothing with her'. They decided to go because Sorokin needed to leave the country and renew her ESTA visa. With them went a personal trainer and a videographer to document the trip 'for fun'. The trip was without hiccups for several days until the staff at La Mamounia insisted on putting a credit card on file because Sorokin had booked their trip without one. Williams was forced to hand hers over. She had $410 in her checking account at the time, she wrote in her article last year. When they returned to New York and Sorokin failed to pay her back, she reported her to the police and then to the district's attorney's office. Sorokin is shown during the pair's 2017 trip to Marrakesh and the Atlas Mountains in Morcco Staff at La Mamounia, a five star resort in Marrakesh, confronted her several times about not paying. Eventually, Williams had to put the charges on her own credit card In her Vanity Fair article last year, she wrote: 'Seeking reimbursement from Anna became a full-time job. Stress consumed my sleep and fueled my days. 'My co-workers saw me unravel. I came to the office looking pale and undone. 'The reality of Anna’s behind-the-scenes dealings, these figures flying from one account to another, remains dizzying to this day—that she was allegedly orchestrating such elaborate schemes while maintaining a believable, surface cool, wielding her debit cards to pay for dinners, workouts, beauty products, and spa treatments. 'She conjured a glittering, frictionless city—whatever one wanted would be bought, wherever one wanted to go was a cab ride or plane trip away. 'The audacity of her performance sold itself, until it collapsed under the weight of its own ambition.' During her trial, Sorokin has been slammed by the judge for throwing tantrums about her outfits and seeming to care more about the TV and movie interest in her case than the outcome of it. She has pleaded not guilty to fraud. Her alleged scheme worked by getting money from one bank to secure a line of credit with another then depositing bad checks into bank accounts and transferring the sums before they bounced. It allowed her to live lavishly in part until she was eventually caught. Among the charges she racked up was a $30,000 stay at 11-Howard, a $12,000 stay at The Beekman, $62,000 in Morocco and other restaurant and party bills.
