Kelley Lynch, Leonard Cohen’s former manager and partner, has been jailed for 18 months for harassing the singer-songwriter.
Kelley Lynch, 55, was found guilty by a Los Angeles court last week, after a sending a torrent of expletive-strewn emails and letters to Leonard Cohen.
She was also sentenced to five months probation and ordered to attend anger-management courses.
Leonard Cohen, 77, thanked the court for the “even-handed and elegant manner in which these proceedings have unfolded”.
“It was a privilege and education to testify in this courtroom,” he told an LA county superior court judge.
Kelley Lynch is not likely to spend her full sentence behind bars due to prison overcrowding in California.
She served as Leonard Cohen’s manager for 17 years, and the pair had a brief relationship.
But Leonard Cohen fired, and then sued, Kelley Lynch in 2004 over the theft of millions of dollars from his personal fortune.
A judge ordered Kelley Lynch to pay $9.5 million in damages, but her lawyers claimed she was unreachable and the money was never repaid.
Leonard Cohen, whose best-known songs include Hallelujah and Suzanne, later came out of retirement, in part to rebuild his finances.
Kelley Lynch’s campaign of harassment started soon after she was fired.
The court was shown binders of emails Kelley Lynch had sent Leonard Cohen, some of which ran to 50 pages.
In a statement made before the sentencing, Kelley Lynch accused prosecutors of carrying out a “vicious attack” on her.
However, she added: “I do believe that I have engaged in excessive and unauthorized rambling.”
“It gives me no pleasure to see my onetime friend shackled to a chair in a court of law,” said Leonard Cohen, “her considerable gifts bent to the service of darkness, deceit and revenge.”
UPDATE: On January 22, 2014 Leonard Cohen’s former manager Kelley Lynch was returned to jail to serve an additional 6-month sentence for violating the terms of her April 17, 2012 probation imposed following her conviction and 18-month sentence for harassing the singer-songwriter. Among other things Lynch was found by the court to have sent threatening, abusive and harassing emails to her trial prosecutor, Deputy City Attorney Sandra Jo Streeter and other attorneys in Ms. Streeter’s office.
