Miranda Kerr, 29, proves once again why she's a Victoria Secret Angel!

The Australian stunner appeared completely nude on the cover of Harper Bazaar's September issue, wearing only a come-and-get-it pair of knee-high boots.

The released photograph, which was a black-and-white shot, was taken by 46-year-old American fashion photographer - Terry Richardson.

Kerr, who has an 18-month old son with her actor husband, Orlando Bloom, keeps her toned figure by watching her diet and exercising. She admits motherhood has served as the ultimate motivation.

"Becoming a mother has made me even more aware and more passionate about nutrition and wellness," the Australian beauty told Harper Bazaar.

She also has "a real appreciation and passion for good health and organic living. I adopt the 80/20 rule. " she continued. "80% good, 20% indulgent and that works for me and my body personally."

Her daily routine consists of drinking "...warm water and lemon every morning and I also drink lots of good quality purified and preferably alkaline water throughout the day," Kerr explains. "My Nan introduced me to Noni juice when I was twelve years old, which I drink twice daily. I treat myself occasionally and don't have any guilt or conditions placed on it. Food is my friend and consistency is the key."

Kerr also explains that she follows  "Dr. Peter D'Adamo Blood Type Diet," which instructs followers to eat according to their blood types. "It's an eating and living guideline that understands you as a biochemical individual . . .and I find it really works for me. I eat vegetables, ocean caught fish, and small amounts of organic free range chicken."
