Keeping up in the Caribbean!

Six-months pregnant Kourtney Kardashian had her two-piece at the ready for a late-March getaway to the Dominican Republic -- where the second-time mom-to-be was accompanied by her entire family, including son Mason, 2, beau Scott Disick, siblings Kim, Khloe and Rob Kardashian plus Kendall and Kylie Jenner and parents Bruce and Kris Jenner.

As exclusive photos in the new Us Weekly (out now) reveal, Kourtney, 32, wasn't shy about revealing her pregnant bod in a sexy tie-dyed bikini during the clan's stay at a 35,000-square-foot villa on the Casa de Campo complex (which rents for $6,000 a night).

"She's a little bigger this time," Kim, 30, tells Us of her oldest sibling, who first broke news of her second baby-to-be with Disick 28, with Us Weekly. "But she still looks amazing!"


Says a source of the trip: "Everyone had a blast!"
