Though reports say that Kendall Jenner and Kylie Jenner have been feuding for years, she still gets along with her other sisters.
Both Kourtney and Kim joined her for some steamy selfies.
But neither of them could quite measure up to Kendall's outrageous, up-close mirror belfie.
"Sunday’s for the girls," Kendall captioned the photo that you're about to see.
Sharing it on Instagram, she flaunts her supermodel booty for all to see.
Wearing a barely-there bikini and a matching animal print hat, Kendall twists her slender torso and snaps a mirror selfie.
Front and center is her butt, which is what makes this a belfie.
But, as you will notice as you look at this photo for yourself, she is not alone.
Who else is there for Kendall's photo but her eldest sister, Kourtney.
Kourtney is leaning forward and gazing into a different mirror.
Instead of animal print, she is sporting a vibrant neon yellow.
Kourtney is not quite as made up as she would be for modeling photos. She's wearing a cap and is dressed for comfort.
But when Kourtney said that Sundays are for spending time with her sisters, she didn't just mean the eldest of the bunch.
Kendall and Kourtney were joined by Kim.
This is a great opportunity to remember how much taller than her sisters Kendall is.
The trio appear in this mirror selfie, flaunting and admiring their looks.
"Can cowboys cry," Kim Kardashians' enigmatic hat queries.
That's definitely a good conversation-starter.
In addition to displaying their gorgeous looks, the three sisters are reminding followers that they have enough shoes to equip a small army.
Looking at any photo of Kendall, you can see why she makes Ben Simmons horny AF.
Kendall may have a scaled down version of the famous booty sported by sisters like Kylie and Kim.
But some say that her more modest proportions make her more relatable to people whose butts will never break the internet.
But also, Kendall is just super hot.
Despite what her critics say, it was much more than her family name that made her one of the most in-demand supermodels on the planet.
Some may be tempted to say that alliances are forming among the Kardashian sisters.
Khloe and Kylie have always been especially close, despite their sizable age gap.
Both were ridiculed for their looks early on in the family's fame, and both underwent the most dramatic total body transformations.
In the mean time, Kendall and Kourtney are both a little more subdued in comparison to some of their more gregarious family members.
By hanging out with Kendall and Kourtney, was Kim picking sides or playing favorites?
Despite rumors of Kendall and Kylie feuding, the two are close sisters and also business partners.
Kylie is now a new mother, and that has taken her life in a very different direction.
Kendall loves Kylie and she loves her many nieces and nephews, but she is still modeling and, you know, actually enjoying her life.
All of these sisters love each other, even if their busy schedules mean that they can't all flash their butts in front of the same mirror.
