Taylor Swift has filed legal papers to have evidence in her slander lawsuit kept confidential.

The Shake It Off star is currently fighting legal action from former radio host David Mueller, who claims he lost his job at Denver, Colorado's KYGO station after Taylor falsely accused him of touching her butt backstage during a meet-and-greet at a 2013 concert in the city.

The 26-year-old singer countersued for sexual assault and battery in October, 2015 insisting she is telling the truth, and asked for a jury trial to resolve the matter.

Last week (ends14Oct16), a motion was filed in Colorado seeking to keep evidence of the alleged incident, including a photograph, and her motion for summary judgment under seal.

"Exhibit 14 is extremely personal and sensitive in nature and should not be shared with the public until absolutely necessary (at trial)," the motion reads.

"In addition to the likelihood of these documents swaying a jury, it is all but assured that the photograph will be shared for scandalous and prurient interests - reasons that have nothing to do with the public's interest in the Court's decision making," it continues. "Ms. Swift's privacy outweighs the public's interest in accessing Exhibit 14 and any documents describing it."
