'10 Years': Courteney Cox, David Arquette Developing Relationship Show For ABC

Well, the experts always do recommend that you write what you know.

Courteney Cox and David Arquette, who separated last October after 11 years of marriage, have remained more than amicable, spending time together, praising each other and raising their daughter, Coco. It also seems that the pair have been keeping up their business relationship, too. According to TV Line, the pair, through their Coquette Productions production company, is in development on a sitcom that would track the ups and downs of relationships over the course of a decade.

Cox would only work behind the scenes, though Arquette -- who is on this season of "Dancing With The Stars" -- could feature on screen in the show. They both appeared in this year's "Scream 4."

Since their split, and some difficult substance-based times for Arquette, the pair has been open about their admiration and affection for one another. Back in April, Cox told David Letterman that, "I don't know what's gonna happen, I really don't. We're getting along so well that I hate to, like, rock the boat." In March, as Arquette left rehab, she said to "Extra," "Oh my God, I'm so proud of him! Best he's ever looked! He's so cute that I'm like, dude, I don't understand. Really?! Why are you that cute right now?"
