How amicable is the breakup
of Courteney Cox
and David Arquette?
The friendly exes, along with 7-year-old daughter Coco, looked like one big happy family Monday night as Cox and Coco cheered on Arquette in his debut on Dancing with the Stars.
Cox beamed and hugged her daughter in the front row as Arquette and pro partner Kym Johnson performed a dazzling Viennese waltz that got an ovation from the audience and compliments from the judges.
"I was very impressed," said Len Goodman. "You're a dancer."
Carrie Ann Inaba agreed. "I really liked it. There's something about you," she said, delivering just one piece of criticism that the quirky Arquette has likely never heard before. "All you need to do is relax a bit."
At end of dance, Arquette gushed about his daughter. "She's just so beautiful. ... She's the love of my life."
And in the night's biggest awwwww moment, Coco looked at her mom as he spoke about her and appeared excited.
