The 28-year-old model, who is married to John Legend, is very envious of the 'On The Floor' hitmaker's curvy figure and would love to have a bigger butt.
She told the September issue of Esquire magazine: ''I didn't know butts were a thing until I was 23. Then came Jennifer Lopez and people were like, 'That butt is great.' Now you have to have a butt. It sucks for me.''
She added: ''I have a little half-Asian butt, and the more I work out, the more I try to get it bigger, it's just going to get flatter and harder.''
Chrissy loves spending her downtime cooking up delicious meals in the kitchen and claims she never diets, as she once tried a liquid cleanse and hated it.
She said: ''I looked at a Wheat Thin one day and got teary-eyed. You know those cartoons where the head of somebody becomes a turkey? That Wheat Thin looked like a f**king turkey. My mouth was watering.''
The Sports Illustrated beauty, who who will celebrate her one-year anniversary with 'All Of Me' hitmaker John in September, recently admitted they are ready to start a family.
She said: ''We both really want kids... we are not, not trying, I will tell you that.
''As we say it's a fun process... it's definitely going to be a surprise, and a surprise we'd be happy for.''
