Courteney Cox and David Arquette on SaturdayCourteney Cox and David Arquette are trying to keep things as "normal" as possible for their six-year-old daughter during their separation, a source close to the couple tells PopEater.

On Saturday, Arquette joined Cox and their daughter, Coco, at the Old Navy + EBowl Event at the Pinz Bowling Center in Studio City, California, for the Epidermolysis Bullosa Medical Research Foundation, which Cox hosted. The non-profit is raising money for research and awareness for EB, a painful, debilitating genetic skin disorder that has no cure.

Cox and Arquette were "being good parents" by attending the event together, the source tells PopEater. "They're trying to keep things as normal as possible for Coco. They're doing things like this because they are co-parenting and want what's best for her. They're separated. As of this moment, they are not getting divorced. And they are still in love."
