Cougar Town star Courteney Cox and her estranged husband David Arquette have separately filed for their divorce due to ''irreconcilable differences''. However, the Scream stars want joint legal and physical custody of their eight-year-old daughter Coco. The couple first met on the set of the first Scream film in 1995 and married in 1999 after four years of dating but the marriage fell apart in October 2010 leading to their separation. But the stars were still on good terms and Cox said then, ''We are comfortable with the boundaries that we have established for each other during this separation and we hope that our friends, family, fans and the media also show us respect, dignity, understanding and love at this time as well.'' The stars filed the divorce paper on June 8.
