Catherine Zeta-Jones New York sunglasses autopraphs

Looking movie star-glam in a black minidress and matching shades, Catherine Zeta-Jones stopped to sign autographs for her fans before making an appearance on The Jon Stewart Show in NYC, on Thursday.

The Oscar winner has had a dramatic few years off-screen, after seeking treatment for bipolar disorder, announcing that her husband Michael Douglas was suffering from throat cancer, and revealing that their 11-year-old son Dylan has "special needs." But thankfully the Rock of Ages star says they're in a "much better place now."

Zeta-Jones recently told Britain's Stylist magazine: "It does make you stronger because you have some ammunition to be prepared for something else that's going to side swipe you, because it really did side swipe us."

Catherine added, "It's now onwards and upwards. We're onto the next chapter of our lives. As long as we have health and happiness, nothing else matters."
