Birthday girl Kylie Jenner isn't the only one turning heads in Mexico!

This week, Kendall Jenner flaunted her slim bikini body at Casa Aramara, Joe Francis' rental beachfront retreat in Punta Mita, Mexico, where she and friends joined her sister for her 18th birthday trip. Kendall, 19, donned a strapless teal two-piece, made up of a strappy bandeau top and skimpy bottom.

The Keeping Up With the Kardashians star and model was spotted on the beach, wearing a straw hat with her swimsuit, and also boarding a WaveRunner while sporting a blue life jacket. She and the others, including pal Hailey Baldwin, 18, and Kylie's rumored boyfriend Tyga, 25, have this week been spotted soaking up the sun and enjoying rides on WaveRunners and on a luxury yacht.

Kylie, who has been photographed several times during her birthday trip, recently flaunted her own hot beach styles, including a strapless purple bikini and a hot pink one-piece, high-cut, '80s-style Body Glove swimsuit she "borrowed" from mom Kris Jenner!

"Ohhhhhhh so THIS is where my vintage Body Glove bathing suit went!!!!" Kris wrote on Instagram. "@kyliejenner you are grounded! Wait, I can't do that anymore you're 18....#whoworeitbetter #80's #whoknewyouwouldlikemyoldstuff #recycle #love #mexico #acapulco1989."
