Mick Jagger is reportedly “deeply upset” after confidential medical information was revealed during a court battle over a contested insurance claim.

On November 14, the Rolling Stones settled a dispute with insurers over a $12.7 million claim for concerts postponed when Mick Jagger’s girlfriend, L’Wren Scott, died.

However, the Stones expressed concern about private information being made public.

Documents revealed Mick Jagger, 71, was suffering from “acute traumatic stress disorder” following L’Wren Scott’s death.

L’Wren Scott took her own life in March, prompting the Stones to postpone a tour of Australia and New Zealand.

Court documents suggested Mick Jagger was advised by doctors not to perform for at least 30 days.

“We are deeply upset that confidential medical and other private information about members of the band and their immediate family and loved ones has entered the public domain as a result of a US court filing initiated by insurers four weeks ago,” said a spokesman for Mick Jagger.

“This was done without the knowledge of the band or reference to their legal representatives.

“This has only been discovered and reported in the press in the last week, by which time we are pleased to say the insurers and the Rolling Stones had, in fact, settled the insurance claim.”

“No further comment will be made about this matter,” the statement concluded.

The Rolling Stones had taken out a policy to be paid in the event shows were cancelled due to the death of family members or others, including L’Wren Scott.

Underwriters had contested the claim saying L’Wren Scott’s death may not be covered by the policy, arguing that she may have been suffering from a pre-existing mental illness which could invalidate the policy.
