Chrissy Teigen's baby girl is so cute it hurts!

The proud mama posted an an adorable snap of her baby daughter Luna outfitted in a little mermaid ensemble while promoting Vita Coco Coconut Oil. Baby Luna -- we want to be part of your world!

The personality has a partnership with the brand and it seems as though the company gifted the wee one the too-cute get up, which consisted of a pink knitted bikini top and pale green knit fishtail bottom.

We have a feeling even Ariel would be jealous of this look!

The 30-year-old model seems to be pushing her partnership Vita Coco Coconut Oil pretty hard. A day prior John Legend's lady love posted a clip on Snapchat, which showed her rubbing some oil into the 12-week-old baby's foot -- oh and there was that Snapchat with her in a coconut bra!
