Demi Moore and Ashton Kutcher appear to have proved their ongoing divorce battle is actually amicable after they were spotted together in California.

The Hollywood couple split in 2011 and Kutcher filed divorce papers at Los Angeles Superior Court in December (12), while Moore subsequently lodged her own paperwork asking her former partner for spousal support.

Online speculation suggested the pair was locked in a bitter legal tussle, but footage of the stars chatting together at Burbank Airport in California appears to prove they remain on friendly terms.

The actors both attended a technology conference in San Jose and reports they flew back on the same plane before the footage was taken at the airport.

In the film, the stars are seen chatting together as they walk out of the airport before saying goodbye and going their separate ways.

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