Happily married: Chrissy and John were married in September last year in Como, Italy, after eight years of dating. The couple are pictured here walking together in New York on July 12.
The brunette beauty 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.'
Chrissy - who appears as a judge on MTV's new cooking show 'Snack-Off' - also admitted that while she enjoys making healthy home-cooked meals for herself and John, 36, she still finds time to enjoy her favourite fast-food treats.
