This we learned when the married couple spent part of their night exploring the face-swap feature in apps on their phones. Friend and celebrity hairstylist Jen Atkin preserved the moment, posted early Saturday, for posterity.

"I am going to vomit," Teigen, 30, said on her own Instagram, of video of the couple, looking (frightfully, partially) like each other.

"This is so gross," she said in the video. "It's so gross."

Legend, 37, couldn't stop laughing.

And while the face swap feature was only temporary, Atkin offered this possibility for the pregnant Teigen:

"Maybe your daughter will look like that!"
