London: `That 70`s Show` co-stars Ashton Kutcher and Mila Kunis reportedly went on a romantic getaway. Kutcher, 34 and Kunis, 28, took a three-day trip to Carpinteria in California where the rumoured couple were spotted eating sushi and shopping for fruits and flowers, reported a website.

A representative for the ‘Black Swan’ actress said the two were not dating. However a source said Kutcher used to have a crush on Kunis. "He was so in love with her for a while when they worked together. He thought she was a goddess, was always talking about how beautiful she is.

But she was with Macaulay Culkin for a lot of that time and also just generally gave off a not interested vibe. It never happened, but I`m not surprised by this at all," a source said. Kutcher split with wife Demi Moore after six-years of marriage last year and was alleged to have cheated on her with 22-year-old Sara Neal following a party.
