The Cox-Arquette family partied together over Memorial Day weekend at producer Joel Silver's big bash in Malibu.

David and Courteney's daughter Coco, who turns seven in two weeks, seems thrilled to be hanging with her parents. We're loving Court's striped dress and black hat!

Our X17 videographer asked both Courteney and David about partying together ... and BOTH had different answers. Check out the videos!
