She rejected Mueller's testimony that there had been "jostling" to get ready for the photo. "He grabbed my a** underneath my skirt".
U.S. District Judge William Martinez ordered jurors, spectators and the news media to leave his courtroom Wednesday so Swift's attorneys and lawyers for plaintiff David Mueller could discuss undisclosed evidentiary matters.
He was also asked whether it was he who had touched Swift inappropriately, as was alleged in Mueller's testimony.
Mueller initiated the litigation, claiming Swift fabricated the groping story and pressured KYGO to fire him. Coomer called it a lie. First, that Swift must be lying because she didn't immediately ask for help and move away from her alleged abuser, and second, that she didn't "look" like a victim of assault because she didn't look upset in the photo.
Mueller's attorney Gabriel McFarland asked Dent why he did not intervene if he saw the alleged groping.
In September 2015, Mueller sued Swift for the loss of his job and lost business opportunities the accusations and negative publicity have caused.
"I'm not going to allow you or your client to make me feel in any way that this is my fault, because it isn't", she said.
"That guy", she added, pointing to Mueller.
Meanwhile, Furtado isn't the only one offering support to Swift during her trial. "It was just destroying her that she said that", she testified.
Swift said Thursday that someone would have had to have been underneath her to see the actual groping "and we didn't have anyone positioned there". She insisted that, contrary to Mueller's assertion that he may have just grazed her ribs with his elbow, his hand was indeed under her skirt.
Taylor Swift on Thursday testified against former radio DJ David Mueller, whom she has accused of groping her during a 2013 meet-and-greet. Swift's bodyguard and Simbeck are listed as potential witnesses. She's trying to tell people out there that you can say no when someone puts their hand on you. She said she saw nothing happen during the brief encounter and that she and Mueller were rudely confronted and escorted out of the arena that evening. The trial centers on a photograph in which Swift, Mr Mueller and his then-girlfriend, Shannon Melcher, are seen smiling together backstage at the Pepsi Center.
"He stayed latched on my bare ass cheek as I lurched away from him, visibly uncomfortably", Swift said.
Mueller sued Swift, seeking up to $3 million because he was sacked after Swift accused him of groping her. Swift countersued for assault and battery, and is asking for $1.
Mueller is suing Swift after her team told his bosses at country music station KYGO that he had reached under her dress and touched her bottom during a meet-and-greet before a 2013 concert in Denver.
Stephanie Simbeck, the photographer, is believed to have heard Taylor talk about the assault soon after it happened.
As the picture is taken, Mr Mueller's right hand is hidden behind the musician.
Swift has testified that "it was a definite grab".
And in true mic drop fashion, her attorney simply addressed the judge and said, "Absolutely no further questions, your honor". In the counter-suit, Swift claims that Mueller has been fired from on-air jobs twice before and hasn't worked on-air since 2006 (which seems a little off, but that's what the statement said).
