Actor Ashton Kutcher, who has been parading his relationship with actor Mila Kunis around New York City recently, has always had a “thing for her,” sources claim.

Ashton, who separated from actor Demi Moore, has been living with his That 70s Show co-star, while she films The Angriest Man in Brooklyn. “He always had a thing for her,” US magazine quoted a source as saying. While a source said that Kunis “isn’t sure this will last”, the Friends With Benefits actor is “going for it.”
