Hard at work while looking flawless, Miranda Kerr was spotted doing a photo shoot for UK Vogue Magazine earlier today (January 30).

The Aussie supermodel sported a white bikini while posing on the back of a vintage wooden speedboat at Sydney Harbor in Sydney, Australia.

Prior to the photo session, Miranda tweeted, “Have a great day everyone! I’m off to work to shoot uk vogue.”

And coming up on February 15th, Ms. Kerr will be back in Sydney for the David Jones 2012 Autumn/Winter Launch. She’ll walk the runway at the newly-refurbished On Seven along with Samantha Harris, Nicole Trunfio, Alexandra Agoston, and Montana Cox.
