​Courtney Cox is celebrating her daughter Coco with another trip around the sun.

​The proud mom gushed in the caption, writing, "Happy Birthday Co. You are such a wise soul. Funniest person I know and my life teacher.

​"I love you x," Courtney added.

​The 61-year-old actress also posted a throwback snap of Coco from her childhood in the second slide, showing the young Coco clinging on Courtney as they stand in the middle of crystal clear water at a seaside.

​Courtney welcomed Coco with ex husband David Arquette, who also posted a sweet tribute for his daughter on his social media.

​He penned, "I’m so proud to be your papa @cocoarquette_ Happy 22nd Birthday! I know this is going to be a magical world."

​Coco rushed to the comment section under her father's birthday tribute for her and wrote, "I love you so much!!"

​David is now married to Christina McLarty, while Courtney is in a longtime relationship with partner Johnny McDaid since 2013.
