Mila Kunis is "pretty simple" when it comes to relationships.

The stunning actress stars in the new comedy film Ted alongside Mark Wahlberg. The pair play a couple who are celebrating their fourth year anniversary. Mila says she wouldn't expect much in real life.

"I'm pretty simple. If you are thoughtful in your relationship, whether it's your one, two, three, four, five or six-year anniversary, be thoughtful about it. It doesn't have to be grand," she told the UK edition of OK! magazine.

"I think material things come and go, but if someone puts a little bit of thought into what it is that makes you happy, whether that would be bringing you your favourite drink, or getting you your favourite candy bar and bringing your favourite flowers and treating you like a princess every day, then it doesn't matter what you are doing on your anniversary. It really doesn't."

Mila has recently been linked to Ashton Kutcher following his split from Demi Moore. When asked what the most surprising thing a guy has ever done for her, she was quick to refute rumours.

"I can't tell you," she laughed. "God, what can I say? I don't know. There's no boyfriend. Nobody read into this. Everybody relax for one second! There's no boyfriend, let me just make this clear!"
