Working hard while soaking up the sun!

AnnaLynne McCord went to work on Tuesday with her fellow female castmates of 90210, and she evidently hasn't skipped a beat in maintaining her bikini body this summer.

On the Beverly Hills beach set, the modelesque star showed some serious skin in a skimpy black bikini with Brazilian-style bottoms and a teeny black halter top. See more photos from the 90210 set.

The 25-year-old actress opened up to Self last spring to dish on her non-traditional exercise regimen she used to keep her long and lean figure.

"I'm not the treadmill girl--I like to do things that are outdoorsy," she told the magazine, adding that kayaking is her favorite workout for her core and upper body. "And I just started doing Taekwando, where I work with a grand master, and Brazilian Jiu-Jitsu."

Although her bikini body may appear perfect, McCord knows the importance of embracing her flaws too. In May, she tweeted a photo of herself without makeup, blemishes and all.

"I woke up this morning and decided I'm over Hollywood's perfection requirement," she wrote alongside the pic. "To all my girls (and boys) who have ever been embarrassed by their skin! I salute you! I'm not perfect--and that's okay with me!"
