The Sports Illustrated model - who has two-month-old daughter Luna Simone with her husband John Legend - says herself and the 'Keeping Up With the Kardashians' star wore latex and were in no shape or form digitally altered to look skinnier in the promo video for their friend's new song.

The 30-year-old beauty explained: "I was with Kim in the scene obviously. And what I realised is that I need to live in latex. Everyone is talking about how we were all Photoshopped. No, you've never seen anything like latex. What looks like Denim jeans [on Kim] that's latex."

In the racy video, Chrissy can be seen breastfeeding her daughter and she says it was the most "beautiful" experience.

She told PEOPLE magazine: "Luna is in it. But they closed down the whole set because Luna was new. She was maybe four weeks old. they turned off the air. They cleared people out and it was her natural lunch time anyway."

Chrissy says it just so happened to be that it was time for Luna's feed and they decided to capture the natural moment.

She added: "It was like Luna is here, and it's "MILF Money - I would love to capture this moment with her, I think it's beautiful."

She also revealed that her 'All Of Me' singer husband was watching the scenes being filmed.

She said: "They were so accommodating of a newborn baby and John was watching."

Meanwhile, Chrissy recently admitted that she is not in a rush to lose her baby weight.

She said: "You just realise you have to give yourself time and understand that you push out a baby, and it took this long to put on the weight, and it's not going to peel right off, and that's OK."
