Rome, Italy/Calabasas, California - Kim Kardashian got a little wild and wet on vacation while Kourtney sported an itsy-bitsy, teeny-weenie bikini.

Kimmy Cakes continues to enjoy her single life while vacationing in Italy.

On Monday, Kim shared clips of herself water skiing in the ocean on her Instagram story.

However, the fun ride hilariously took a turn for the worst.

The first video showed the KKW owner cruising while being pulled by a motorboat. Yet, seconds later, the reality star splashed into the ocean after losing her balance.

Never one to back down from a challenge, the Kim got right back on the board and managed to stay on this time.

Khloé was also present during the fun outing. Kim tagged her younger sibling in another post while Celine Dion's hit song, My Heart Will Go On, played in the background, a selection which the younger Kardashian sister apparently didn't appreciate.

Kim shared videos of her kids enjoying a water slide, too. Luckily, none of them had a tumble like their mom.

Meanwhile, the eldest of the Kardashian siblings left little to the imagination with her festive swimwear.

While vacationing in California with Travis Barker, Kourtney wore a patchwork bikini GCDS.

The bikini-top featured a red bandana print and green gingham, while the stringy-bottom was blue and black with heart patterns.

Ironically, the Poosh owner wasn't the only celeb to flaunt their curves in the teeny bathing suit.

Dua Lipa wore the same bikini top while enjoying her weekend with her boyfriend Anwar Hadid in New York.

Both also donned a pair of blue jeans, though Kourtney did include a shot that featured the outfit's very skimpy bottoms as well.

Clearly, the Kardashians remain the queens of true vacation style!
