So cute!

But now she's finally at that stage where she understands (and loves) Sesame Street, a rite of passage for every child, even the famous ones.

Well, Luna's dad had the absolute biggest surprise for the little fan when he and all of his Sesame Streetpals put together a personalized video for her while he was playing piano on an episode (Luna was sick on the day of the shoot and couldn't attend). Teigen uploaded the video in December and couldn't wait for the day Luna was old enough to go "absolutely nuts" over it.

And that day is finally here! Luna had the chance to watch her big surprise, and to say she's excited would be an understatement.

She can't believe this is happening -- that Elmo and the gang would actually know her.

Luna giggles and waves to her friends as they all tell her they love her. She even recognizes her daddy amongst the muppets. That smile is truly infectious.

Luna, you have friends for life with these guys. Can't wait for you to meet them in person! We expect a video.
