The 30-year-old model and her husband John Legend, 37, only welcomed their daughter Luna - their first child together, who they conceived via IVF - in April but they're "loving" parenthood so much that they're keen to add to their brood in the future.

A source told E! News: "John and Chrissy do want another baby sooner rather than later. They both always wanted a big family."

The proud parents - who got married in 2013 - underwent years of infertility treatment, which consisted of Chrissy having dozens of hormone injections, in order to have their little bundle of joy.

And the brunette beauty believes she'll have to undergo a similar regime if she and John wish to have more children.

She said recently: "I wish I had frozen my eggs earlier. We have a few more on ice. Who knows what will work?

"It would have been better if I had made a ton of embryos when I was already doing the shots because now I have to do the shot thing again. I think about that."

Meanwhile, although the duo seem to be enjoying parenthood, Chrissy isn't so thrilled about the concept of breastfeeding and has admitted that the amount of milk she has to produce for Luna on a regular basis is making her feel like a cow.

She explained: "The feeding schedule surprised me a lot. If you kind of do the math, you're kind of breastfeeding for 10 hours a day total. It's very loving and sweet, but it's not easy.

"They just use you for your milk and you feel like you are a cow all day. It's hard to work your entire day around getting her all the nourishment she needs because they are just little animals."
