The 'Mad Men' actress -- who is a U.K. size 14 -- revealed she hasn't always been curvy, and put on 15 pounds after treating herself to pasta and cappuccino coffees while working as a model in Europe.
She explained: "I started out as a model and when I went to Italy to build my modelling book I gained 15 pounds from all the pasta and cappuccinos.
"I saw my body change and I loved how it changed my appearance and how it made me look more womanly and sexy."
The 35-year-old beauty admits she has been pressured throughout her career to lose weight but insists she has always been happy with her size.
She told Grazia magazine: "I love my body as it is. People in the industry have been telling me to lose weight for years but I like the way I look. I give credit to my mom for helping me feel good about my appearance -- for making sure I never felt embarrassed about my body, because she was never worried about looking too big."
