Courteney Cox-Arquette and David Arquette have split.
The couple - who have a six-year-old daughter, Coco - agreed to a trail separation several months ago after 11 years of marriage but insist they "still love each other deeply".
In a joint statement they said: "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."
It is thought the couple have already agreed to a joint custody deal to share parental rights of Coco.
The former 'Friends' actress and the 39-year-old actor met on the set of 'Scream' in 1996 and were married three years later.
Last year, Courteney, 46, revealed the couple had therapy to get help for the problems in their marriage, adding: "We have the same arguments we've had for years."
