"Mad Men" star Christina Hendricks is putting her famous curves front and center again -- flaunting her assets for the new issue of Cosmopolitan UK.

The 36-year-old bombshell, best known as Joan Holloway on the hit AMC show, barely squeezes into a tight gold dress for the magazine's February issue, where she talks about being called "sexy."

"It's incredibly flattering and surprising, and I didn't think for a second when I started Mad Men that people would talk about me as being sexy or a pin up," says Hendricks. "My husband has a good laugh about it, of course."

So what does sexiness mean to her? "Sexiness is about confidence and individuality. I can't keep my eyes off the women you see in cities like London, New York and Paris - the way they carry themselves and put themselves together are always so unique. Sexiness is about being an individual and having conviction about what that is."
