Opening statements are due to begin later at the civil trial involving Taylor Swift and a former US radio presenter she accused of groping her.
The singer claims she was sexually assaulted during a meet and greet before one of her concerts in June 2013.
Swift told the Associated Press “he took his hand and put it up my dress and grabbed onto my ass cheek.”
David Mueller's suing the popstar for 3-million dollars, saying he lost his job because of the allegation which he insists is false.
Swift is counter-suing for one dollar saying she wants to hold him to account.
The singer is due to testify later this month.
