A US woman accused of stalking actress Catherine Zeta Jones wrote a letter of apology to the star, her lawyer said.
Catherine Zeta Jones' staff contacted police
Dawnette Knight, 32, wrote to Zeta Jones and father-in-law Kirk Douglas for apologising for any "distress" she may have caused.
Ms Knight has pleaded not guilty to making criminal threats and stalking is being held on $1m (£554,800) bail.
The letter, released by lawyer Richard Herman, said she was infatuated with Zeta Jones' husband Michael Douglas.
"I was a confused young woman infatuated with Michael
Douglas and have not rational explanations for my
actions," she wrote.
Ms Knight was arrested at her Beverly Hills home on 3 June and charged with one count of stalking and 24 counts of criminal threats.
Dawnette Knight is due in court on 29 June
Zeta Jones staff had called in police, alleging the actress had been receiving threatening letters and phone calls.
Ms Knight is being held in custody and could receive a prison sentence of up to 19 years if convicted.
Her letter to Zeta Jones said she would "have never done anyone any harm and would never
harm anyone" but admitted her obsession with Michael Douglas.
"It would be a wonderful good deed if you would all forgive me so that I can go back to college to finish my studies in child psychology," she pleaded to the actress.
Ms Knight remains in custody and a preliminary hearing has been set for 29 June.
