Alec Baldwin allegedly has a stalker on his hands.

Canadian actress Genevieve Sabourin, 40, was charged with aggravated harassment and stalking after she showed up to Baldwin's Manhattan apartment building, law enforcement sources told the New York Post.

The 30 Rock actor, 50, who was recently engaged to 28-year-old yoga instructor Hilaria Thomas, called police on Sabourin after the doorman from his Manhattan apartment called him to notify him of the creepy visitor, the Post reported.

Baldwin was at his Hamptons residence at the time.

Sabourin worked with Baldwin on the 2002 movie The Adventures of Pluto Nash, where Baldwin had a cameo and Sabourin had a minor role.

The Canadian actress allegedly tried to meet Baldwin by showing up to his Hamptons home, an event he was hosting at Lincoln Center and his Manhattan apartment, according to the New York Daily News.

Baldwin is just the latest celebrity to have a creepy stalker. Here are five other stalking victims:

1.       Lindsay Lohan (Lonnie Short)

In January, Lonnie Short, a 64-year-old man, allegedly trespassed on Lohan's Venice Beach, Calif. Home, knocked on her door and demanded to speak to her, according to TMZ.  

Short was arrested on charges of trespassing and held on $1,000 bail, reported thehollywoodgossip.com.

2.       Uma Thurman (Jack Jordan)

Uma Thurman has had to deal with her creepy stalker, Jack Jordan, for years.

The unstable Jordan, a former psychiatric patient, terrorized the Kill Bill actress by showing up to the set of My Super Ex-Girlfriend in 2005 with a postcard in his hand that said My hands should be on your body at all times, according to ABC News.

Jordan, who was sentenced to three years' probation and forbidden from contacting Thurman in 2008, also allegedly called Thurman's cell phone. The actress testified at the 2008 trial.
