Taylor Swift is going to court against a DJ she says groped her — here's what you need to know

Mueller sued Swift in 2015, saying her accusation that he groped her butt during a meet-and-greet in 2013 caused him to lose his job.

Swift countersued Mueller a month later.

Two years after Mueller and Swift sued each other, their case is about to go to trial.

Here is everything you need to know about the impending trial:

Mueller filed a lawsuit claiming that false groping accusations from Swift got him fired.

Mueller sued Swift in October 2015, alleging that false claims he had groped Swift at a meet-and-greet resulted in his termination, according to The Denver Post.

Mueller had been invited to Swift's meet-and-greet when the singer was performing at the Pepsi Center in Denver on June 2, 2013.

Mueller attended as a part of his a job as a DJ on a local morning show.

Mueller and his girlfriend took a picture with Swift, and shortly after Swift's security found Mueller and accused him of groping her.

Mueller was fired two days later.

While Swift never spoke publicly about the incident, the radio station was sent the picture that Swift said documented Mueller groping her. A representative for Swift told People: "The radio station was given evidence immediately after the incident. They made their independent decision."

Two years after Mueller was fired, he brought a lawsuit accusing Swift of making false accusations that resulted in his firing. In the suit, Mueller said he had met "hundreds of celebrities" in the past and has never been accused of anything like this previously.

Swift filed a countersuit one month after being sued by Mueller.

One month after Mueller sued Swift, she filed back with a countersuit, according to People.

In Mueller's lawsuit, he accused his boss Eddie Haskell of being the one who actually touched Swift inappropriately.

But Swift's countersuit dismisses this allegation:

"Resolution of this Counterclaim will demonstrate that Mueller alone was the perpetrator of the humiliating and wrongful conduct targeted against Ms. Swift, and will serve as an example to other women who may resist publicly reliving similar outrageous and humiliating acts."

The countersuit continues to claim that Mueller reached up Swift's skirt and with purpose groped an "intimate part of her body in an inappropriate manner, against her will, and without her permission."

The intimate part of Swift's body mentioned in the counterclaim is her behind.

Marie Claire confirmed this when it released portions of Swift's deposition from July 26, 2016, in which the star described Mueller grabbing onto her "ass cheek."

Swift also requested a jury trial in her countersuit and declared that any money won would be donated to a charity that fights against, and protects women from, sexual assault.

Swift's mother will be a witness her during the trial.

Andrea Swift, Taylor Swift's mother, has been named as a witness in the case and can be expected to testify in court, according to People.

Taylor's photographer who captured the Swift said Mueller grabbed her, is also expected to take the stand, in addition to a senior member of her security team.

Thirty-two seats will be held for members of the public interested in watching the trial.

According to TMZ, only 32 seats will be held for members of the public interested in attending the trial.

The public will be allowed to begin lining up to attend the trial at 6 a.m., with tickets to enter the court handed out at 7 a.m. A viewing room set up with monitors to watch the trial will have 75 seats.

Though she recorded a video deposition on July 26, 2016, Swift is expected to testify in court.
