Jennifer Aniston is proving she'll always be there for her bestie's whole family.
After Courteney Cox shared adorable throwback pics to social media to celebrate daughter Coco Arquette turning 17 on Sunday, June 13, Jen followed suit as she posted photos of herself with the teen for the special day.
One shot from years ago featured the 52-year-old star of The Morning Show with a broad smile while holding up the girl, who is Jen's goddaughter and appeared to be about to lovingly hold the actress' face. "Happy birthday my sweet Cocolicious!" Jen captioned it.
Another image showed the two Friends alums, who recently appeared together on the long-running sitcom's HBO Max reunion, posing together while a seemingly sleepy Coco was sucking on one of her own fingers. Jennifer simply used three smiling-with-hearts emojis to caption that one.
Earlier in the day, Courteney had posted a carousel of photos featuring Coco, her only child with former husband David Arquette. The former couple split up in 2010.
"Happy 17th birthday to my strong, sensitive, creative, loving, soulful, beautiful, talented, and wise Coco," Courteney captioned it. "I love you so much."
The 56-year-old Cougar Town alum also shared her support for Coco on her Instagram Story that day by writing, "Happy birthday to my coconut. She's the best kind of nut!"
For his part, David posted an image to his Instagram account on June 13 of a much-younger Coco wrapping her arms around him. The 49-year-old Eight Legged Freaks actor captioned it with three heart emojis.
