Courteney looked on with pride at her talented daughter
Back in June, both of Coco's proud parents paid sweet tributes to her on social media as she marked her birthday.
The Monica Gellar actress took to Instagram to share a series of photos of herself with Coco taken at various stages in her life – from baby to teenager – and wrote: "Happy 17th birthday to my strong, sensitive, creative, loving, soulful, beautiful, talented, and wise Coco. I love you so much."
David, meanwhile, shared a sweet video of Coco as a toddler, which also featured Courteney.
Courteney and daughter Coco are incredibly close
Despite Courteney and David no longer being together, the pair have remained on good terms, with the actor opening up about their relationship in an interview with Yahoo Entertainment in August.
He explained: "We're friends, and we've communicated a lot because of Coco. We've just had - not an easy time with it, we've just been really open and supportive of each other."
He added: "We never went head-to-head, [or] battled each other, through the process of divorce and through the process of raising our kid. So it's made for a friendship and relationship that is out of respect."
