Mila Kunis has slammed "absurd" rumors she is anything more than friends with Ashton Kutcher.

Speculation mounted that the That 70's Show co-stars had taken their friendship to the next level after they were spotted shopping for furniture together and taking a three-day mini-break in California. However Mila, 28, considers reports she is dating the Two and a Half Men actor to be ridiculous.

"It's very absurd. I've never commented on my personal life - I'm not going to start commenting on my personal life now. But it's a friend. A friend is a friend," she told Extra.

However, sources claim Ashton, 33, used to have a huge crush on her. "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," the insider told People.
