The 38-year-old Australian actress stripped down to a racy red bikini, which showcased her washboard abs and ample assets.
In the image, Nicky looks off camera and smiles as she poses in her costume.
She also flaunted a soft golden tan and had her short locks out in tight curls.
Nicky is not shy when it comes to showing off her figure and regularly posts snaps of herself in bikinis online.
She previously revealed her diet and exercise regime to Muscle and Fitness while training for the action series, Matador.
'As for diet, I eat small meals all day,' Nicky explained.
'I start every day with a green shake in my blender, then follow that with coffee.' She said she 'changes up her training' but likes to keep a 'healthy, happy mind.'
Nicky hails from Melbourne but is based in the US. (Thu 6)
