The “Poker Face” singer has been ducking deposition demands by producer Dr. Luke in his defamation case against singer Kesha, according to court papers.

Kesha, who accused Luke of sexually assaulting her, dished about the incident to Gaga via text messages in 2013, calling Luke a serial rapist.

Luke is suing Kesha, claiming she falsely accused him of drugging and raping her – and wants Gaga, whose real name is Stefani Germanotta, to turn over the texts.

When Dr. Luke subpoenaed the messages from Germanotta earlier this year she replied with a “Heavily-redacted, four page spreadsheet of the text messages,” says Jeffrey Movit, a lawyer for the producer, in a new Manhattan Supreme Court filing.

“To accommodate these concerns” Movitt said he’d “Limit the deposition to no more than three hoursand offered to take the deposition on any date during the weeks of August 7 and 28 in Los Angeles and New Yorkgiven that Ms. Germanotta apparently will be performing in those cities during those weeks.”

So he plans to ask a Manhattan judge in court on Aug. 8 to order Germanotta to sit for the legal grilling.

“This motion has become necessary because Dr. Luke’s counsel has not been able to obtain, despite repeated request, a deposition date from Lady Gaga,” the lawyer said.

“Dr. Luke’s team is attempting to manipulate the truth and draw press attention to their case by exaggerating Lady Gaga’s role and falsely accusing her of dodging reasonable requests,” Sean Cassidy said.

Kesha first sued Dr. Luke in 2015 claiming he gave her date rape drugs, assaulted her on an airplane and then at his home between 2005 and 2008.
