Alec Baldwin's stalker has been jailed for six months.

Sabourin claims to have had a sexual encounter with Baldwin in 2010, something Baldwin denies. Two years later, she proceeded to ring and email Baldwin. She was finally arrested in April 2012 when she turned up at Baldwin's Manhattan apartment. Baldwin's then-fiancé, now wife, Hilaria asked their doorman to contact the police.

Sabourin, a 41-year-old Canadian actress, maintained she was "innocent" even after Judge Robert Mandelbaum ruled against her. She also verbally abused Baldwin when he took to the stand on Tuesday (12th November), as a result of repeatedly interrupting his testimony she was sentenced to one month jail time. The judge then ruled she should spend a further six months in prison.

Baldwin is not the only celebrity to have been plagued by an overly ardent fan. A worryingly large number of fans became obsessed with celebrities and take their infatuation to terrifying and dangerous levels.
