Martina McBride
Age: 54
Fountain of Youth: With a bikini body even a teenager would envy, Martina is certainly disciplined. She also keeps her look fresh by framing her baby blue eyes in flattering hairstyles, from choppy bobs to long waves.
Her Secret: The mom of three tells Shape magazine that she became “fascinated with nutrition” when she was pregnant with daughter Delaney. “I love to read about healthy eating and preach to my husband, who doesn’t listen! Now I’m trying to teach it to my daughters.”
