David Arquette and Courteney Cox's recent separation isn't going to get in the way of family Halloween tradition.

At Hollywood's Roosevelt Hotel Friday for the AMP Energy Juice Short Film The Legend of Hallowdega, Arquette, 39, told reporters about his plans to spend the spooky day with his estranged wife and their daughter Coco, 6.

After partying (in an Elvis costume) in Vegas with pals on Saturday, Arquette will "come back" to L.A. on Sunday, he said. He, Cox, 46, and Coco will "go trick-or-treating."

And the whole family -- not just their little girl -- will dress up, Arquette added. "Coco is going to be a bumblebee and Courteney is going to be a sunflower...I'll put on a flower suit."

On Wednesday, Arquette overshared -- again -- about his trial separation from Cox in his second candid appearance on Howard Stern's Sirius Satellite Radio show. The actor admitted he was "crying" the first time he had sex with another woman following their separation. He's also "drinking a little more" since their split. (Married for 11 years, the couple announced their trial separation Oct. 11.)

He was slightly more discrete on Live with Regis and Kelly the same day. "We're at very different places," he said of their marriage. Is there a chance for reconciliation? "There's always a chance. I love her with all my heart."
