Heroes hottie Hayden Panettiere  showed off her glowing skin last night (February 24) as she headed out for a night in Hollywood. Hayden was seen making her way to the Kantor Gallery for an event. Hayden also rocked the latest bold-lip trend with some red lipstick, along with a slouchy grey cardigan as she made her way into the gallery and out of the rainy Los Angeles weather.

So how does Hayden keep her body in such tip-top shape? Swimming! Hayden recently dished on her latest work out plan for her feature in this month’s Shape Magazine. “Swimming works all your muscles—your core, glutes, quads, even the ones you didn’t know you had, like the little ones in your feet and hands! It’s about getting your heart rate up and building endurance. You can hold your breath much longer than you think you can.”
