The 40-year-old actress called the cops after the man reportedly demanded to see her and refused to leave her until he met her. He had showed up on her doorsteps with flowers, reported TMZ.
The incident took place on Sunday, October 5.
The actress asked him to leave the flowers at her gate but he insisted to hand them to her personally.
Keira Knightley faced a similar incident when an unwanted admirer disrupted her Broadway debut by throwing a bouquet of flowers and shouting "Will you marry me?" before being removed.
