Princess Diana’s former lawyer is representing Meghan Markle in her ongoing lawsuit against Mail on Sunday.

Meghan is suing the British tabloid paper and its parent company for publishing a letter she wrote to her father Thomas Markle. The civil lawsuit accuses the outlet of copyright infringement, misuse of private information, and violating the U.K.’s data protection law with the publication of the letter.

A pre-trial hearing took place Friday, with lawyer David Sherborne helping to fight Markle’s case.

Sherborne’s law firm biography confirms he’s worked with the likes of Harry Styles, Paul Weller, Chelsea Clinton, Paul McCartney and many more famous faces in the past.

Harry has previously mentioned his late mother and her battle with the press when talking about his wife Meghan.
