Knicks guard Derrick Rose says his ex-girlfriend — who lost her civil case accusing him of rape — for trying to duck his demand for legal fees, saying she brought a “fake case” that’s taken an “irreparable toll on [his] public image.”

Under federal law the winner of a civil trial is able to ask the court to force the loser to cover costs like photocopying, transcription and witness fees.

Rose made a request for $70,000 from his accuser earlier this month after a jury cleared him of rape and related charges brought by a woman he dated off and on from 2011 to 2013.

The 30-year-old woman balked at the demand saying she was broke. She filed the $21.5 million civil suit against Rose in 2015 before reporting the 2013 incident to cops.

An LAPD spokesman told The Post that a criminal investigation into the rape claim is ongoing. “There has been no determination by the district attorney here as to whether it will proceed,” the spokesman said.

In a new court filing Rose’s lawyer Courtney Palko said the woman has plenty of resources, noting that she owns a home and multiple cars including a Cadillac.

“Plaintiff’s own trial expert Dr. Elena Konstat cited [her] ‘abundant resources’ and ‘life goals,’ along with her education and degrees, as evidence that she was not faking her rape claim for money,” Palko says in court papers.

Meanwhile Palko said that her 28-year-old client “is responsible for the financial support of several family members and friends.”

“Mr. Rose is in the final year of his professional basketball contract.” she said.

The accuser, who plans to appeal, claims Rose and two of his friends forced themselves on her when she was passed out after a long night of partying in August 2013.

Her “aggressive pursuit of false claims in this court and in the media have taken an enormous, costly, and irreparable toll on Mr. Rose and his public image and reputation,” Palko said.

A majority-female jury took less than four hours to decide in favor of Rose and his two pals after a nearly three-week trial in October.

“The outcome in Mr. Rose’s favor was swift, decisive, and unanimous on all claims ,” Palko said.

An attorney for the accuser did not immediately respond to a request for comment.
