So amicable it's almost confusing!

For his Dancing with the Stars debut on Monday, David Arquette had two lovely ladies cheering the loudest for him: his daughter Coco, 7, and estranged wife Courteney Cox.

"I thought David did such an amazing job," Cox, 47, told Us Weekly after the show. Arquette, 40, and partner Kym Johnson scored a middling 18 out of 30 points for their Viennese waltz. "It's the most nerve wracking thing I've ever experienced and I'm so proud. I loved it. He had such grace and such style," Cox added.

The Cougar Town star added that Coco loved being part of the special night. "She is really excited to be here -- she is proud of her dad. It was really fun for her."

"It meant a lot to have [Courteney] and Coco here tonight," Arquette told Us.

After 11 years of marriage, Cox and Arquette announced they were separating back in October 2010. But while both have since been frank about their marital woes -- and Cox spent a high-profile vacation in the company of sexy Cougar Town costar Josh Hopkins -- they've remained completely friendly.

Indeed, perhaps even Coco herself isn't always clear about her parents' dynamic lately. In one interview, Arquette gushed of his daughter: "She's the light of my life!"

Overhearing, an excited Coco turned to her mom and said "He's talking about you!"

"No," Cox said, correcting her. "Dad's talking about you!"
