Teigen posted photos of Luna in a variety of adorable costumes, and each one was more aww-inducing than the one before.
"Have you ever seen a more 'why me?' face 😭 ," the "Lip Sync Battle" host captioned the photo of her 6-month-old, who is clearly shooting the photographer a look in the pic.
Teigen could barely control her giggles for Luna's next look (a tiny baby peacock!) captioning her Instagram video of the costume, "You can't possibly think I only bought the hot dog."
Luna's next look ― an all-pink Minnie Mouse costume complete with ears, a big pink bow and a pink Disney princess Halloween basket ― looked like it was Teigen's followers' favorite getup.
"I can't cope," one follower said, trying to deal with all the adorableness in one photo. "OMG I love that one, she looks so damn cute," another added.
The supermodel was clearly having a hard time controlling her emotions, captioning her photo, "Please help I can't stop."
Thank god she didn't stop.
Though the supermodel has yet to declare a winning costume from the four choices Luna modeled, it may be because she has a few other looks for her little one to try out.
Post all the pics, Chrissy!
