Courteney Cox is obsessed with work.The former 'Friends' actress, who worked with her actor husband DavidArquette on US TV series 'Dirt', struggles to leave work behind when she gets home. Courteney said: "Yes, I do bring things home. It's time to catch up, because when you have been working together, you don't really have time to talk about what happened."At dinner, there is a lot of catching up to do, even though we have seen each other most of the day. It's weird."While the 43-year-old admits she is very different to David, Courteney insists their contrasting personalities make the show more interesting. She explained: "David and I are very different, and have different creative choices and different creative views."He is really left of centre - it's amazing what he comes up with. I'm good with emotions and psychology of people. He is good with other creative aspects - like thinking up Don's hallucinations. Don is a paparazzo who is schizophrenic."The couple have a three-year-old daughter, Coco, together.
