Though Courteney Cox and David Arquette have separated, the two, accompanied by daughter Coco, were nothing but smiles at the Old Navy Rock & Bowl event at Pinz in Studio City, Calif., on Saturday
"They looked super amicable," one eyewitness tells PEOPLE. "Courtney and David were high-fiving each other after Courteney bowled."
As for their 6-year-old, "Coco was cheering on her mom," the eyewitness also observed. "Everyone was laughing and looked very happy to be there together."
The icing on the cake: The two adults happily posed for photos together.
