Chrissy Teigen's heart aches out of love for her newborn daughter Luna.

She captioned the sweet image: "Bath time is tooooo cute! My heart, it hurts (sic)”

The beauty welcomed Luna Simone Stephens with her husband John Legend, 37, on April 14 and shared their happy news with their followers on social media two days later.

And fans can expect to see many more pictures of Luna as she grows, because the model previously insisted that they won't be hiding her away.

She said: "I am conscious of what people want to see and what they don't want to see, or what they see through completely.

"We're not going to go out of our way to hide because obviously it's such a big part of our lives to show everything: the inside of our homes, my parents living with us, our animals, everything. I'm not going to do sneaky back shots of her or anything."

Chrissy even took to Twitter to joke about the effects of childbirth, quipping: "no one told me i would be coming home in diapers too (sic)."
