According to the Belfast Telegraph on Friday, Jones, who plays Betty Draper on the hit AMC show, says that her off-screen personality is totally different than what people see on the small screen.

She said, "I'm hilarious at home. It's not like I stopped being funny ten years ago. If you get my sisters and me together as a unit, well, we'll each say we're the funniest one. But I'm the eldest, so they had better say I'm the funniest."

Just recently, Jones said that being a model helped give her a "thick skin" in life and especially in her Hollywood career.

According to the Belfast Telegraph last week, the blonde beauty says that being a model was a "cliché" start to her career, but also the best move she's ever made in her life.

She said, "You develop a thick skin because you learn rejection seven or eight times a day. I knew I didn't want to be a model. People in the fashion industry are brutal. But what it did give me was a knowledge of my own body, of how to move in a way that works, of things that look good on me."
