She's not taking this lightly.

Taylor Swift appeared in a Denver federal courthouse on Tuesday, as her trial against former radio DJ David Mueller got underway. The songstress has accused Mueller of grabbing her butt backstage during a meet-and-greet at the Pepsi Center in 2013. He was subsequently fired, and countersued for $3 million in lost wages and damages.

"Today Ms. Swift is taking a stand for all women. Today a woman has reported being sexually assaulted and now she is being sued for a case of workplace sexual assault. She has been in tens of thousands of meet-and-greets, including going out in the crowds, and she never had this happen. If a person cannot stand up and serve as an example to other young women that have been sexually assaulted, then who can?” Swift's lawyer J. Douglas Baldridge said in his opening statements, per Us Weekly.

T-Swizz is determined to make an example out of Mueller, but only plans to take one cent - yes, one! - if she wins the case.

"This was an assault and Ms. Swift reported that it happened. There is overwhelming photographic evidence showing what happened. The accused has an alibi, but he only came up with it two years later. He wants to make the victim pay the price, he is seeking 15 times what his contract with the radio station was worth in damages, and Ms. Swift is seeking $1 to show women you can say no," Baldridge added.

Mueller denies any wrongdoing.

"He is here to clear his name and he unequivocally denies he touched her inappropriately in any way. There was no inappropriate contact that is Mr. Mueller’s position," his lawyer Gabriel McFarland countered.

Don't expect her to shake it off!
