The 'Lip Sync Battle' star insists she hasn't "snapped back" since giving birth to daughter Luna - her first child with husband John Legend - in April and admits though she looks "great" on the outside thanks to her Spanx and waist trainers, she is still "soft" underneath her clothes.
She told People magazine: "I'm not back yet by any means.
"I think people think that I've snapped back, but I really have just in fact been utilising undergarments more than ever.
"I never was a Spanx person or a waist trainer person. Now I do it. It looks great on the outside, but trust me, I'm a bit soft."
The 30-year-old beauty features in Fergie's new video for her single 'M.I.L.F.$.' and credits her sexy appearance to a flattering fabric.
She said: "Everybody is talking about how we were all Photoshopped. No, latex is another being. You've never seen anything like it.
"Latex gives where it needs to give and cinches where it needs to cinch. It's like magic. Latex is magic."
In the racy video, Chrissy can be seen breastfeeding her daughter and she says it was the most "beautiful" experience.
She said: "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."
The brunette beauty 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."
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."
