COURTENEY COX ARQUETTE and David Arquette have announced their separation, after 11 years of marriage.

In a joint statement they said that they’re still friends and responsible parents for their daughter, six-year-old Coco:

We have agreed to a trial separation that dates back for some time. The reason for this separation is to better understand ourselves and the qualities we need in a partner and for our marriage. We remain best friends and responsible parents to our daughter and we still love each other deeply.

As we go through this process we are determined to use kindness and understanding to get through this together. 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 pair have also reportedly decided to maintain a business relationship, and will star alongside each other in the upcoming Scream movie due for release in 2011.
