Nearly two years after Demi Moore announced her marriage to Ashton Kutcher was over, the couple has yet to make it official. Though Kutcher finally took the first step and filed divorce documents in December 2012, stalled negotiations have prevented the former couple from being able to go their separate ways.

According to the website, the fact that Moore, 50, and Kutcher, 35, were spotted walking and talking together after landing at Burbank Airport could mean big things for their divorce. The pair were both attendees at the same tech conference in San Jose, Calif., and they flew back on the same plane together.
