Just another day at work!

Australian model Miranda Kerr shared two sexy bikini Instagram photos of herself Thursday posing in a tropical location.

In on photo, Kerr, 29, poses directly in front of the camera in a stunning coral and gold bikini standing in the clear ocean water. She captioned the image, "50 shades of Miranda…" possibly making a reference to the erotic bestseller Fifty Shades of Grey. A second photo is of Kerr's full toned body in an ultra-sexy zebra-print bikini.

Kerr is the proud mother of son Flynn, 17 months, with husband Orlando Bloom, whom she married in July 2010. The family of three recently enjoyed a vacation on the beach in Bora Bora in May.

The model said her secret to losing the baby weight so quickly was breastfeeding -- which she had to balance with work.

"I am breastfeeding and pumping," she told Sydney's Herald Sun after giving birth in January 2011. "When I am at work, I am pumping. I feel like a milk maid, but it is worth it."
