Ashton Kutcher and Demi Moore: post-its help to keep the flame

In the interview, Ashton Kutcher revealed he wrote post-its to keep the flame alive.

“If you go to our house, I have post-it notes placed in various locations all with messages of encouragement or love or just thought,” Moore said. “Some have been there seven years.”

“Post-it notes are much cheaper than diamond rings,” added Kutcher.

On a more serious note, Moore explained that “you have to make your relationship a priority–and that’s a difficult balance when you have work and, you know, the combination of a career and family. I think we spend very little time apart–that’s one of the key things.”
