Taylor Swift Accused of Slander During Radio DJ Lawsuit

Former KYGO radio host David Mueller claims he was fired from his job after Taylor Swift falsely accused him of groping her at a backstage meet-and-greet, and now he's saying she has slandered him during their legal battle.

In June 2013, Mueller attended a backstage meet-and-greet with Swift, along with his girlfriend/co-worker Shannon Melcher. The couple took a photo with the superstar and later that night a member of Swift's security team approached Mueller and accused him of touching her inappropriately.

Mueller was fired from KYGO two days after the concert, according to his complaint, and sued Swift in September.

"The contention that Mr. Mueller lifted up Ms. Swift's skirt and grabbed her bottom, while standing with his girlfriend, in front of Ms. Swift's photographer and Ms. Swift's highly trained security personnel, during a company-sponsored, VIP, backstage meet-and-greet, is nonsense," wrote Mueller's attorney M. Gabriel McFarland in the amended complaint.

Swift countersued for assault and battery in October, seeking damages arising from "the undisputed fact that a sexual assault was committed against" her.

Mueller claims his then-boss Eddie Haskell bragged about grabbing Swift's buttocks that night and told him "he and one of his friends in the industry think Ms. Swift must wear bicycle shorts under her stage outfits."

Swift's countersuit says she knows exactly who committed the assault.

"It was Mueller -- and she is not confused in the slightest about whether her long-term business acquaintance, Mr. Haskell, was the culprit," wrote Swift's attorney J. Douglas Baldridge in the countersuit. "Resolution of this Counterclaim will demonstrate that Mueller alone was the perpetrator of the humiliating and wrongful conduct targeted against Ms. Swift, and will serve as an example to other women who may resist publicly reliving similar outrageous and humiliating acts."

In an amended complaint filed last Thursday, Mueller added two slander claims to his arsenal, claiming Swift's statements are false and have caused harm to his reputation, profession and standing in the community.
