Summer came early for Kim Kardashian! The reality star is currently on vacation in a secret location — and she wasted no time showing off her insane curves in an itty-bitty red bikini.

In a series of videos on Instagram, Kim rocked the two-piece while showing off her 24-inch waist. And she seems to be in a competition with sister Kourtney Kardashian, who was recently spotted in Turks & Caicos with boy toy Younes Bendjima, as to who can rock the smallest bikini. Watch the video above to see all the sexy snaps from Kim's tropical getaway!

It's no surprise Kim is showing off her hard-earned curves. The 37-year-old has been working out non-stop since last year, and recently shared her diet and exercise secrets with fans. "It's so important to work out your core!" Kim wrote on her app. "My trainer Melissa [Alcantara] and I have been doing really intense ab workouts — and even though they're SO hard, I love the end result."

However, her trainer reassured fans the KUWTK star has no plans to lose her famous curves. "Kim told me, ‘I love my body. I love the way it looks and I love my hips.' She just wanted more muscle. She wanted bigger hamstrings, which accentuates the entire leg. And she wants those cut arms and abs!" Melissa told People magazine. "She didn’t want to be skinny. She wanted to have muscle and feel strong. And she wanted to find something she can do for the rest of her life."

Last year, unflattering photos of Kim surfaced during a family trip to Mexico, and she is determined to not let that happen again. "I've been living too hard core in the gym for that to ever happen to me again," she tweeted at a fan who brought up the snaps. "So far its been very private, no paps in site. But don't worry we've been taking tons of pics. I will post them when I have time." We can't wait to see them!
