On Friday, Teigen posted a pic of Luna cuddling into her bare chest via the app, which she later posted to Instagram.

"#nofilter," she joked, as you can clearly see that the app's popular flower crown filter had been used.

In another adorable post, the 30-year-old model played around with the dog filter, using the animated tongue to make it look as if she were licking her sleepy newborn.

And implying that she's already feeling a bit tired from her new mom duties, Teigen wrote, "I don't remember what makeup feels like" over a photo that was snapped using a filter that creates jewels around the eyes and bright pink gloss on the lips.

Even Luna's grandma, Vilailuck Teigen, got in on the fun, laughing hysterically as she and her daughter attempted to master the face-swap feature.
