Alec Baldwin has slammed his alleged stalker on Twitter.

Canadian actress Genevieve Sabourin, 40, appeared in a New York court on Monday accused of stalking and aggravated harassment of the 30 Rock actor after he reported her to police but Alec lashed out at her for smiling as she was led away in handcuffs.

"Isn't it odd when an accused stalker is in handcuffs, being taken away by the cops, yet smiles for the cameras?" he wrote on his Twitter.

Alec also wrote a message to his fiancee, 28-year-old yoga instructor Hilaria Thomas, praising her for her support: "I am lucky and grateful in my life now, no matter what the motivations of certain others. @hilariathomas (sic)."

"Its a 2way st, amor. This woman has taken up enough of our time & energy. Now we have to trust the judicial system that they will protect us (sic)." she replied.
