Idle hands be damned, Kaya chooses to keep her schedule booked. “I am a workaholic,” she says. “I’m self-motivating and have high standards, morals and great ambition.” The German-Irish beauty started college when she was 14 years old—to have time to major in everything that interested her—then took on the world of modeling and acting. When it’s time to veg out, Kaya likes to make popcorn and watch movies at home with her puppy. “When my energy spikes,” she says, “I let it out on a great run, hike or go rock climbing.”
