Luna, who was born in April this year, is looking up at her dad in the clip before she giggles while her mum holds her hand. In another part of the clip, the married couple kiss their daughter on each cheek.
Fans of the singer were quick to praise the cute video, with one writing: "My heart cannot take it!"
Another added: "You are a beautiful couple and family. What a gorgeous little girl. I hope you have many more."
John loves playing music to his daughter, and Chrissy shared a video of him playing a "never ending song" on the piano to her while she held Luna in her arms.
The model also recently had fans laughing after dressing little Luna up in a range of different, hilarious costumes for Halloween, including a hotdog, little Red Riding Hood and a Pink Lady from Grease.

Joking about Luna's range of costumes, the Lip Synch Battle host wrote: "Please help I can't stop."
She then revealed that she had been sent more costumes for her daughter, writing: "Ok that is a wrap on costumes. Some were sent to us from very kind vendors but we are going to donate them all tonight so other families can get the same joy out of them.
"Tomorrow's adventure: john's FIRST pumpkin carving. How on earth??!?!!?"
