Mueller, who went by the name "Jackson" on air, sued Swift after he was sacked from his $150,000-a-year job on June 4, 2013 - two days after the alleged groping.
The former radio host who was sacked for allegedly inappropriately touching pop star Taylor Swift is only suing her for money and fame, Swift's attorney said Tuesday in opening statements of their civil trial.
Swift, one of the most successful contemporary music artists, earned $170 million between June 2015 and June 2016, following a world tour and her best-selling "1989" album, Forbes Magazine said. Taylor is expected to take the stand during the trial in U.S. District court to testify about the incident, which resulted in broadcaster David Mueller's firing from Colorado music station KYGO-FM. She wore bright red lipstick and had her light brown hair pulled back in a bun with full bangs.
The groping incident took place on June 2, 2013, during a meet-and-greet session before her concert in Denver.
Swift, 27, says that broadcaster David Mueller slipped his hand under her dress while they posed together at one of her concerts in 2013.
Mueller, who denies the allegation, was sacked from his $150,000 a year job as a morning host at radio station KYGO two days after the alleged incident.

Her son was rushed to the hospital, but he was reported as conscious and breathing when EMS arrived at the scene. That's when two people inside the auto chased her down on the interstate, shooting at her vehicle.
According to Associated Press, Swift is attempting to keep her legal battle "discreet and quiet and confidential", with Swift's attorney, Douglas Baldridge, arguing in court that she was particularly upset by Mueller's claim that "for some reason she might have some incentive to actually fabricate this story".
"Let's be clear about something from the onset - inappropriate touching is offensive, it's wrong and should never be tolerated", said Gabriel McFarland, Mr Mueller's lawyer, in his opening statements.
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.
They are also each expected to testify at some point during the trial.
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. While she's only seeking $1 in retribution, she said she hopes her lawsuit serves "as an example to other women who may resist publicly reliving similar outrageous and humiliating acts".
There are also questions about whether jurors were fans of Mueller on local country radio station KYGO. Officials expect the jury to be seated and opening statements to begin on Tuesday. Bell and Andrea Swift are also defendants in Mueller's lawsuit.
