Red hot! Kim Kardashian showed off her killer bikini body in an eye-catching string two-piece during some downtime in Punta Mita, Mexico on Saturday, Aug, 16.

The Keeping Up With the Kardashians star, 33, showed off her famous curves in the cleavage-baring swimwear while paddleboarding with a friend. She's currently spending time at friend Joe Francis' house Casa Aramara.

North West's mom seems to be more confident in her body than ever, despite admitting earlier this month that she wanted to lose 15 to 20 pounds. "No more excuses. my baby is 1 years old! UGH. I'm not gonna call it baby weight bc thats an excuse. i just gained weight & that's it," she tweeted on Aug. 5. "Just need to get down to my weight a few years ago."

Clearly, Kardashian meant business. Just two weeks later, the star showed off her 7-pound weight loss during a "waist training" session via Instagram. "#hourglass #waisttraining #nophotoshopnecessary @premadonna87," she captioned a pic of herself on Aug. 21. Days earlier, she shared a glimpse of her impressive figure again in a black halter dress during a Mexican night out with her "sexy man" Kanye West.
