It might be a bittersweet feeling, but January Jones is finally ready to say good-bye to her on-screen character Betty Draper in the hit AMC drama, Mad Men. The Hollywood actress opens up about playing the controversial mother on the show and how she's ready to move on - both physically and emotionally.

In a new interview with InStyle Magazine this week, Jones says that the first change she is going to make is her hair.

She said, "I haven't been able to grow my hair long for eight years. My hair's been through the ringer."

Jones also says that her new film Good Kill was a comedic relief compared to the intensely rigid Betty that she plays on the show.

Jones explained, "I hadn't read anything that made me laugh like that, ever. It was a nice way to be emotionally relieved of the pressure of Betty, and also just to remind people that I'm not Betty."

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."
