Chrissy took to Snapchat to share highlights from their fun outing, which included a pic of "auntie" Kim sweetly holding the 6-week-old in her arms.
The Cravings author then panned her camera over to Kanye, who was all smiles as he stared into the newborn's eyes. (Yes, we got a smile from the "Famous" rapper!) Kim stayed close to her husband's side, still admiring precious Luna.
It appears the rest of the day was an entire family affair, as Chrissy and John's dogs also made an appearance on the 30-year-old model's Snapchat story -- in a little red wagon!
Luna is no stranger to social media or being the center of attention, as she's already made a ton of appearances on her mom and dad's various social media accounts. Watch the video below to see an adorable snap taken of Luna during bath time.
