Chrissy Teigen and John Legend's adorable daughter Luna Simone just turned one, and two days later she got to celebrate Easter with her parents' besties, the Kardashians.

Chrissy and her baby girl headed over to Kim Kardashian West's house on Sunday, where Luna got to hang out with Kim's kids, Saint and North West, as well as Kourtney Kardashian's super cute children and some giant Easter bunnies.

Chrissy, Kim, Kourtney and their friend Jen Atkin also posed for a photo with some petting zoo animals that they had over for the celebration, which Kim shared to Snapchat.

Little Luna couldn't have looked happier playing with some plastic eggs after the traditional Easter egg hunt.

She also seemed to be having a wonderful time hanging out with her mom and the Easter bunny on Kim's perfectly manicured lawn.
