Four years ago Taylor Swift accused DJ David Mueller - then co-host of KYGO's Ryno and Jackson radio show - of groping her at a meet-and-greet event.
Now, the 27-year-old is now expected to take to the stand during civil court proceedings scheduled to begin this week.
In her deposition last year, Swift described the incident in detail, explaining how in 2013 the Denver disc jockey allegedly reached his hand up her skirt and groped her backstage at her concert at the Pepsi Centre in Denver.
'Right as the moment came for us to pose for the photo, he took his hand and put it up my dress and grabbed onto my ass cheek and no matter how much I scooted over it was still there,' she said, according to Billboard.
'It was completely intentional, I've never been so sure of anything in my life,' she added, according to the transcript of Swift's videotaped deposition.
Immediately following the incident, Swift reportedly informed her mother, Andrea Swift, and members of her team of the alleged sexual assault. Two days after the alleged groping, Mueller's employers at KYGO reportedly fired the DJ.
According to pre-trial legal documents obtained by CNN, Mueller launched a law suit in 2015 claiming Swift and her co-defendents (including her mother), falsely accused him of improperly touching the star, and is currently seeking £2.3 million in damages.
Swift subsequently filed a counterclaim against Mueller and denies complaining to his employer, as he asserts.The singer's filing states it was her radio promotions director, Frank Bell, who alerted KYGO to the alleged incident.
Taylor is now expected to testify in the civil court this week, with opening statements thought to begin on Tuesday, according to the Hollywood Reporter.
Bell and Swift's mother are also expected to testify with Taylor, as is Lorraine Bayard de Volo, chair and associate professor of women and gender studies at the University of Colorado, who will offer expert testimony on the conduct of and ramifications for victims of sexual assault and harassment, CNN reports.
Hoping the case serves as 'an example to other women who may resist publicly reliving similar outrageous and humiliating acts', Swift has vowed that if she wins the case, she will donate any money she received to 'charitable organisations dedicated to protecting women from similar acts of sexual assault and personal disregard'.
The case continues.
