Apple's smart app Siri is apparently involved in an unusual face-off with Scarlett Johansson, who has lent her voice to a self-aware OS in Spike Jonze-helmed sci-fi romantic film 'Her' that becomes the lead character's object of affection.

According to PVR Pictures, when users ask Siri to say something about the movie, the intelligent personal assistant replies saying that the 29-year-old actress portrayal of artificial intelligence is beyond artificial. When the blonde beauty was asked to comment on Siri's denouncement, the actress joked that she feels betrayed.

Johansson continued saying that the other day she asked Siri how she looked, Siri said that she was the fairest of them all. She added that Siri was obviously playing both sides and called the unique Operating System a backstabber.
