Mila Kunis is calling her boyfriend Macaulay Culkin her “steady rock”.

Kunis has been dating the “Home Alone” actor since 2002 but the two are rarely seen out together and often refuse to discuss their romance with the media.

But Kunis said Culkin plays a huge role in her life because they’ve grown up together, surviving several difficult periods and the trappings of Hollywood at one another’s side.

“I don’t know if I met him at 27 if it would have been a different relationship. We grew up together. You find a steady rock in your life and that’s all you need. We have our ups and downs, but work through them,” she told Women’s Health magazine.
