Fact: Kim Kardashian truly looks amazing after giving birth to daughter North West last year.
And while her loved ones are ecstatic for the reality star bouncing back to her pre-baby weight, they're also annoyed by how much she boasts.
In a new clip for the upcoming episode of Keeping Up With the Kardashians, Khloé and Rob join their sister for a workout.
Kim Kardashian Steals the Spotlight From Khloé on Her 30th Birthday
The two trail behind the 33-year-old bombshell, who's on a roll doing lunges as she walks up steps.
"Everyone do a squat in between the stairs," the 33-year-old says to her siblings as she does the movements.
"You think you're hot sh*t, don't ya?" Khloé says back. Meanwhile, poor Rob is seriously trailing behind.
In a confessional, the 30-year-old, who lost an impressive 30 pounds last year, tells cameras, "It seems like Kim set up this hike to kind of showcase her energy. She is moving and grooving.
"All Kim does is talk about fitness and what she's eating. I just feel like everything kind of is a competition."
Keeping Up With Kim Kardashian's Kleavage
As Khloé attempts to keep up with her older sister, their now-estranged brother stands back and watches them. (Later in the clip, Kim talks about her visit with a psychic, who tells her she'll have another baby "very soon" and that Rob isn't "bi-polar.")
As it's been reported, Rob has been on the outs with his family ever since he decided to opt out of attending Kim's Italian wedding back in May. The 27-year-old sock designer flew back to LA from Paris following a verbal dispute with his famous siblings and momager, Kris Jenner.
