Actress Mila Kunis and her fiance Ashton Kutcher laughed off claims by an upcoming pop star Kristina Karo, who has sued Kunis for stealing her pet chicken 25 years ago, in Ukraine. The couple does not seem to be moved by the $5,000 lawsuit and instead posted a video on iPhone app Meerkat ridiculing Karo’s claims.

"Let's just get this clear. You stole a chicken from a one-month-old child who spoke to you in an entire conversation? It's just shocking to me,” Kutcher says, addressing Kunis, in the video, which was posted Wednesday, adding: “Speaking in English in one month? This is the smartest girl I've ever heard of,” Mirror reported.

The couple continue to suggest, in the video, that the story is fabricated. Kutcher says: "So this girl has a music video coming out at the same time she's suing you for $5,000 for the stolen chicken when she was one month old and you were seven?"

Karo has claimed, according to TMZ, that 25 years ago, when Kunis was in the first grade in Ukraine, they were close friends and that the “Friends With Benefits” star stole one of her pet chickens named “Doggie.” She also claims that Kunis confessed the theft to her and said, “Kristina, you can have any other chicken as a pet, you have a whole chicken farm."

Karo said, according to TMZ, that she became an emotional wreck after the incident and had to go into therapy. Karo has reportedly claimed that her childhood memories have begun haunting her again since she moved to Los Angeles -- where Kunis also lives -- to make a career in singing. The $5,000 claimed by Karo in the lawsuit is to cover her visits to the psychiatrist and the emotional distress she has suffered, according to TMZ.

Kunis also mocks the lawsuit in the video, according to Mirror, and says: "I was devastated. I was weeping. I was dumbfounded,” adding: “I was like, which chicken did I steal? I was obviously in the village when I stole these chickens so I apologized to this woman who may or may not have been a month old.

"I would like to launch a counter $5,000 lawsuit for making me watch that music video. My body hurts. My eyes hurt. They're burning,” Kunis reportedly says, adding: "I feel like I will be a chicken fighter for a very long time. I would never steal somebody else's chicken."

Kutcher reportedly ends the video by defending Kunis: "I believe this woman (Kunis). I know her very well. I believe she's an ethical person that wouldn't steal chicken. You heard it right from the chicken's mouth."
