Mueller is seeking $3m in damages after losing his $150,000 salary.
Jury selection began Monday in the civil trial involving musician Taylor Swift and a former KYGO DJ who is accused of groping her.
One man who ultimately was not selected told U.S. District Judge William Martinez on Tuesday that he was not necessarily a fan, "but her music is catchy and it's good vibes". Taylor, dressed in a white top and black jacket, sat at a table with her mother, Andrea Swift, and her attorney.
On Tuesday, jurors were shown a photograph of the alleged assault at a VIP room meet-and-great before the gig on 2 June 2013.
According to the litigation filed against the DJ it has been reported that Mueller slipped his hand under Swift's dress and grabbed her backside as they posed for a photo-shoot before the concert.
The deejay, David Mueller, has sued Taylor, saying her accusation that he groped her during a meet-and-greet in 2013 is false and caused him to lose his job.More news: Israel attempts to shut down Al Jazeera's office and ban journalists
Swift countersued the 55-year-old shock jock for assault and battery, claiming that her reps informed the radio station about the incident but didn't demand Mueller be fired.
Mueller denies anything inappropriate occurred during the brief backstage encounter in which he stood on one side of the pop star and his girlfriend on the other.
The trial between singer Taylor Swift and former radio host David Mueller carries on into its second day as lawyers prepare to make their opening statements.
They are also each expected to testify at some point during the trial. He recalled being kicked out of Swift's concert by her tour manager.
In the suit, Swift said she not only wants to hold Mueller accountable, but also hopes to "serv [e] as an example to other women who may resist publicly reliving similar outrageous and humiliating acts". Her suit argues that KYGO terminated Mueller after its own independent investigation.
Mueller often appeared to be reading documents while Swift watched the proceedings closely, occasionally conferring with her counsel.More news: 72nd anniversary of 1945 Hiroshima bombing observed in Japan
They were questioned specifically about their familiarity with either Swift or Mueller and whether they considered themselves to be fans of their work.
Swift never went to the police. She says she does not know Mueller and has no incentive to target him or to fabricate a story.
Jury selection began Monday.
The case is being heard in federal court because Swift and Mueller live in different states - Swift in Nashville, Tennessee, Mueller in Colorado - and damages at stake exceed $75,000.
Swift said, "It was not an accident".
Mueller's attorney, Gabriel McFarland, disputed Swift's allegations.More news: Gunmen Attack Church In Southeastern Nigeria, 8 Killed
