The `Mad Men` actress - who is a UK 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."
