Ashton Kutcher, Demi Moore Spotted Together in Los Angeles

Amanda Edwards/WireImage(LOS ANGELES) -- Ashton Kutcher and Demi Moore are not back together but they were spotted walking together at LAX after landing in Los Angeles following their attendance at a tech conference for their joint venture, We Are Thorn. 

The organization, which was originally called the Demi and Ashton Foundation when it was created in 2009, aims to use technology to "effect positive changes in the world."

A source tells E! News, "Demi did not want to be photographed together, but Ashton convinced her to walk with him."

According to Thorn's website, the company’s goal is to "disrupt and deflate the predatory behavior of those who abuse and traffic children, solicit sex with children, or create and share child pornography."

Kutcher tweeted Monday night about the conference, writing, "Thank you to everyone on the @thorn tech task force. Your dedication and pursuit of a better world will echo for generations."

Kutcher and Moore split in November 2011 after six years of marriage. Their divorce is not finalized.

Kutcher is currently dating his That '70s Show co-star Mila Kunis.
