The 'Made to Love' singer and the model, who wed in September last year, are planning on starting a family soon, and want to end up with a large brood.
Chrissy told ABC news: ''We definitely have plans for kids. I want a ton, he wants a ton, so I guess it's time to start.''
Although Chrissy may be ready for kids, the part she isn't too keen on is actually being pregnant.
She added: ''I just wish they appeared. I just wished they just showed up out of nowhere.''
Chrissy also said she and John have been enjoying married life so far, although she's not comfortable with him leaving the bathroom door open when he goes to the toilet.
She added: ''It's the same, it' sexier, is that what you want me to say? It's so much sexier! Everything's better and bigger! Maybe we're a little more open with the bathroom.
''I am like, 'Babe. Take this back a notch. I cannot keep doing this. I want to pee separately. No more doors open.' ''
