Kylie Jenner was not just busting out of her bikini during a recent vacation in Costa Rica.
She also busted out some serious public displays of affection with long-time boyfriend Tyga.
In need of a break from her stressful life of plumping her lips and posing for selfies, Kylie and various other family members descended on this tropical locale over the weekend.
Along with sisters Kim Kardashian, Khloe Kardashian, Kourtney Kardashian, Jenner spent more of her time in a two-piece bathing suit, finding the best angle with which she could highlight her cleavage.
But Kylie also made time for Tyga, throwing her arms around him and holing his hand at different points in the trip.
The vacation included Tyga's son, King Cairo; along with Kourtney's kids (Mason, Penelope and Reign), as well as hairstylist Jen Atkin and makeup artist Ariel Tejada.
Based on Snapchat evidence, these stars didn't even pay for the vacation.
Cameras were on hand to record footage for future Keeping Up With the Kardashians episodes, meaning E! very likely footed the bill.
In return, fans were treated to one sultry snapshot after another, with Kim remaining mostly silent... but Kylie and Kourtney picking up the revealing slack.
Heck, Kourtney's body was on full display throughout the extended weekend.
And while Kylie also found plenty of time to pose in a seductive manner, she also found time to cozy up to her older lover. To wit:
"Jungle Bae," Kylie wrote as a simple caption to the above image.
Jenner and Tyga actually appear to be in a very stable place these days.
We haven't heard any breakup rumors involving the couple in months. We've barely heard anything about them at all!
It's almost as if this relationship is real and boring (from our point of view) and not simply invented for the sake of reality show ratings and headlines.
(Yes, we were thinking of you, Rob Kardashian and Blac Chyna, while writing that sentence.)
Here's a look, for example, at Kylie and Tyga simply holdig hands and looking happy:
Most talk centered around Kylie of late isn't relevant to her romance, but rather to her chest.
A random plastic surgeon believes the teenager has undergone a boob job, despite constant denials by both Kylie and her mother.
Still only 19 years old, it's more likely that Kylie just experienced a growth spurt in this area over the past couple years than she underwent any sort of medical enhancement procedure.
But you never can say for certain with these people.
And it's Kylie gives fans little choice but to discuss her boobs when she poses for photos in outfits such as this:
Even Kim Kardashian might tell her half-sibling to calm down with the cleavage upon seeing this picture.
Okay, probably not. She's probably the one who picked out the ensemble in the first place.
Are you buying Jenner and Tyga? Do you think their love is for real?
And what about those Kylie Jenner breasts? Are they for real?!?
