Kylie's rumored beau Tyga is joining the ladies on their tropical vacation after he and the youngest member of the Kardashian-Jenner clan showed some PDA for the first time in Mexico last Friday. Kylie was spotted picking him up from the airport in that same bikini top and unbuttoned shorts.
Earlier on Tuesday, the girls' older sister Khloe got in on some ATV action with Kendall. They rocked attire not typically seen on ATV excursions as Khloe wore a tight black dress with a high slit while Kendall wore a printed bikini top with a matching thigh-baring skirt.
Kim and Kourtney Kardashian were not seen on the ATVs with them, but they still showed off their St. Barts styles. Kim, 34, flaunted her baby bump in a skin-tight, black maxi dress, and Kourtney rocked a short white dress.
While it's swimsuit weather there, they're definitely taking St. Barts by storm!
