Lady Gaga has found herself at the centre of the ongoing legal dispute between Kesha and her former producer Dr Luke.

The producer – whose real name is Lukasz Gottwald – has accused the singer of defamation over her claims she was sexually assaulted by him.

A statement, released by his lawyer over the weekend said, Gaga was being sent a subpoena because she has information regarding “false statements about Dr. Luke (pictured below) made to her by Kesha”.

It added the subpoena was “necessary because Dr. Luke’s counsel has not been able to obtain, despite repeated request, a deposition date from Lady Gaga.”

In a statement of her own, lawyers for Lady Gaga – who has been a vocal supporter of Kesha – told Variety, “she has provided all of the relevant information in her possession”.
