Pop star Taylor Swift is “absolutely certain” she was groped by a Colorado radio DJ, a court has heard.
Ms Swift, 27, accuses broadcaster David Mueller of slipping his hand under her dress while they posed backstage together at one of her 2013 concerts.
Her lawyer said in his opening statement at the court in Denver, Colorado, that Mr Mueller had “grabbed her rear end”.
Mr Mueller sued the singer in September 2015, calling her allegation false.
He said she had cost him his $150,000-a-year job as a host at country station KYGO-FM.
Ms Swift – who was in court on Tuesday – countersued a month later, saying what occurred at the city’s Pepsi Center was assault and battery.
On Tuesday, jurors were shown a photograph of the alleged assault.
In the picture, Mr Mueller and his then-girlfriend, Shannon Melcher, stand with Ms Swift in the middle.
All are smiling, and Mr Mueller’s right hand is hidden behind the Shake it Off singer.
Mr Mueller’s lawyer, David McFarland, said in his opening statement the image shows his client’s hand “is not underneath Miss Swift’s skirt, and her skirt is not rumpled in any fashion”.
”David Mueller unequivocally denies he touched her inappropriately in anyway,” Mr McFarland said as his client looked on in court.
”Falsely accusing someone of inappropriate touching is equally offensive, equally wrong and should not be tolerated.”
But Ms Swift’s attorney, Douglas Baldridge, told the eight jurors: “What’s wrong with this picture? A woman gets assaulted, a woman reports it, and she gets sued.”
He added: “It’s not inappropriate touching. It’s assault.”
