David Arquette with his daughter Coco
If anyone's been keeping a close eye on Dancing with the Stars
this season, it's contestant David Arquette's daughter Coco.
The adorable little one – with mommy Courteney Cox
in tow – cheers on her dad
from the sidelines of the ballroom each week, and has even started providing her own commentary on some of the judges' criticism.
"She says sometimes the judges have on their cranky pants," Arquette, 40, told PEOPLE of his daughter, 7, backstage after Monday night's show
. "She says, 'Let's hope they have on their happy pants.' "
The doting dad, who has made his devotion to Coco
clear throughout the season, also showed off a tattoo he got in her honor.
The body art, which says, "I love mom and dad," is from the first note Coco ever wrote to her parents on her own.
"I got it when Coco was about five," Arquette explains, adding that he doesn't "wear too many sleeveless things," which is why some people noticed it on Monday night for the first time.
