David Arquette and Courteney Cox‘s marriage is on the path to being officially over. After 11 years of marriage, Arquette, 40, filed divorce papers in a Los Angeles Superior Court on Tuesday, according to People.
The couple initially announced their separation back in October 2010 — and now, Arquette is citing irreconcilable differences as the reason for the split. He is also seeking joint physical and legal custody of their daughter Coco (who actually turns 8 tomorrow!).
Even though Arquette and Cox have decided to go their separate ways, they claim to still be on good terms. “He’s my favorite person in the world,” Cox, 47, said back in January. “He’s my best friend. No matter what happens in our future, he’s my very best friend.”
