One thing's for sure ... the Kardashians are one close knit family!
Khloe Kardashian took to Instagram to share a pic of her famous booty in a new pair of super snug NYDJ jeans, revealing that she made brother Rob Kardashian take the snapshot.
"That awkward moment when you make your brother the photographer lol! Thanks @NYDJ for the amazing jeans! Love the fit. Love the lift," the "Keeping Up With the Kardashians" star captioned the photo.
And Khloe's revealing snaps didn't stop there. The 31-year-old reality starlet also posted an image where she's seen licking Kendall Jenner's abs -- yes, really.
"I missed her so much and those abs were irresistible!!!! #SisterSister," she wrote on the social media site.
In the pic, the duo is sporting workout gear at celebrity trainer Gunnar Peterson's gym. Kendall is covering her grin as Khloe gets a taste of her tight tummy.
These ladies certainly have been spending a lot of time at the gym ... and it shows!
"I try to work out five days a week," Khloe told E! News in April, adding that she lost 13 pounds in three months by cutting out dairy. "It's a lot, but I feel great when I do it."
