Giovanni Palumbo pleaded guilty in September to criminal harassment.
He'd been in custody since being arrested at Canada's Juno awards in March, where he showed up with a greeting card to give to Twain. That was after trying to reach her many times before.
Now Palumbo is on three years of probation. He's not allowed within a-half of Twain, her family or anyone who works for Twain.
He's also not allowed to contact her or communicate with her and has been ordered to continue counseling. His lawyer says the man has a mental health issue.
Twain had testified by video link and described the lovelorn letters Palumbo had mailed to her homes in Ontario and Switzerland and said she felt fear and vulnerability. He even showed up at her grandmother's funeral.
