Molly Sims -- Sun-Kissed Bikini Babe!

It’s not that easy being green -- unless you’re super sexy Molly Sims.

The 36-year-old actress/model looked tanned and toned as she strutted her stuff in a green colored bikini top and dark bottom poolside at a uber chic hotel in sun-kissed Mexico on Wednesday.

The gorgeous Vegas star -- who recently split with hunky actor Aaron Eckhart -- is currently working on a new independent drama called Hickory Nation. In the film, Sims plays a teacher in a small Maine coastal community, suddenly caught up in a mysterious hit-and-run, along with two of her students, each struggling with secrets and lies. Kris Kristofferson will play Sim’s father.
