Nicole Kidman has been named the global ambassador for Australian health and wellness brand Swisse, and judging by the first photos from her ad campaign, it's not hard to see why!

With her hair twisted up, the Academy Award winner, 45, wears a variety of summery looks while posing serenely outdoors. Swisse's expansion will begin in the United States in January before it debuts in Europe and Asia.

"It's exciting to be part of the growth of a small Australian family-built company that is dedicated to good health and well-being," Kidman says in a statement. "I joined Swisse because I wanted to help bring awareness to the importance of living a healthy lifestyle in a busy, often stressful world."

Kidman -- who has two daughters, Sunday, 4, and Faith, 20 months, with husband Keith Urban, 44, and daughter Isabella, 19, and son Connor, 17, with ex-husband Tom Cruise, 50 -- adds that she loves "feeling healthy and fit. They are wonderful attributes of the Australian way of life, and I am a very proud Australian."

Swisse chief executive officer Radek Sali adds that the company is "thrilled" about its partnership with Kidman. "Nicole represents everything the brand is about," he raved. "At Swisse, we focus on health and happiness, and celebrating life every day. We look forward to sharing this message with the world."

Kidman is currently nominated for a Primetime Emmy Award for Outstanding Lead Actress in a Miniseries or a Movie for her role in the HBO period drama Hemingway & Gellhorn.
