How does Victoria Principal look so young?

Former Dallas star Victoria Principal has been spotted by the Daily Mail looking years younger than 59, the age she claims to be.

Speculation surrounding the soap star, who once posed for Playboy, is that she is actually 63 years old and has had a little help to retain her youthful beauty.

According to the Mail, there have been a number of "persistent rumours" that Ms Principal has gone under the surgeon’s knife.

When asked about cosmetic surgery, Principal told the newspaper: "It’s sad when I see a woman who has done things to herself in an effort to look younger, and instead she looks some way she never looked before."

Principal is currently putting herself through a rigorous training regime so she can become one of the worlds first ‘space tourists’, when Sir Richard Branson’s company Virgin begin the trips next year.

Ms Principal begins each day with a two-mile power walk and follows it up with resistance training and yoga, according to the Mail.
