Uh, oh! Do you think Kim Kardashian West and Kanye West could be catching the baby-fever bug again? We can't be sure, but they were sure mesmerized by Chrissy Teigen and John Legend's daughter Luna Simone Stephens, while out with the couple at Nobu in Malibu, California, for breakfast over Memorial Day weekend.

Chrissy posted a video to her Snapchat on Sunday, May 29, 2016, featuring Kimmy cradling the model's still-fairly-newborn daughter in her arms. "Auntie," she captioned the adorable shot. Does Kim not look completely infatuated with the little girl, born in April? (She is pretty darn cute).

Kanye West was also caught gazing at little Luna in another video. Tiny tot Lulu literally fit into the "Life of Pablo" rapper's hands! The couple, who celebrated their 2-year anniversary on May 24, had smiles on their faces as they looked on at her -- yes, even Kanye was smirking.

Kim recently gave birth to her second child, a son named Saint West, on Dec. 5, so maybe Luna will have a built in BFF to play with, close in age.

While we still don't know for sure if Kim and Kanye will have more kids, they do sure keep talking about it.

On May 20, Kim took to Snapchat to document a pregnancy scare, sharing a photo of a negative test that she took on a plane.

And back in April, she appeared on "Kocktails with Khloe" and admitted that Kanye has had babies on the brain, even though she thought they were done. "I was so set on my two kids and how happy I was with my life the way that it is, but Kanye has been mentioning it every single day lately for the last 10 days."

For now, we'll just keep reveling in the cuteness of Kim and Kanye with baby Lu.
