Prospective jurors in a civil trial involving duelling lawsuits between Taylor Swift and an ex-Denver radio disc jockey are being asked whether they are fans of the singer-songwriter or the former host of a country music show.
A 15-page questionnaire released as jury selection began on Monday also asked prospects if they had ever been inappropriately touched, seen Swift in concert, downloaded or purchased her music or were at the June 2013 show where Swift says David Mueller touched her on the buttocks.
Mueller denies any inappropriate contact.
He claims he was fired after Swift falsely accused him of grabbing her and he is seeking up to $US3 million ($A3.8 million) in damages.
Swift countersued, alleging sexual battery by Mueller.
Jury selection was expected to last through Tuesday.
Eight jurors will be picked for the trial expected to last two weeks in federal court.
Security was tight at the Denver federal court. Police and a bomb-sniffing dog waited in the rain on Monday with about a dozen reporters before potential jurors were set to arrive for questioning.
Swift does not have to be in court for jury selection but she does have to be present for the rest of the trial and is expected to testify.
Members of the public can line up to watch proceedings from an overflow room in the courthouse but so far there has not been a big turnout.
