Kim Kardashian West just can't help herself when it comes to making fun of her younger brother, Rob Kardashian.
The 35-year-old reality superstar recently paid a visit to Rob's new home in Calabasas, California -- along with sister Khloe Kardashian -- and documented a little bit of the experience on Snapchat. Kim hilariously gives 29-year-old Rob a hard time about having a copy of her 2015 selfie book, Selfish.
"You guys, look what Rob reads," Kim says sarcastically.
"It's not a reading book, there's no words in it," Rob fires back, before Kim quickly gets defensive.
"There is words, you a**hole," she retorts as the two continue to argue.
Later, Kim and Khloe poke fun at a room in Rob's house that has a wine glass decal on the wall.
"Don't know what this room is that Rob has ... it's really bizarre," Kim notes.
The siblings' mother, Kris Jenner, bought Rob the stunning $2.3 million house in February. The 4,256 square-foot home located in an upscale gated community boasts four bedrooms and five baths.
The location of the new home is also conveniently close to his famous family. Rob's sisters, Khloe and Kourtney Kardashian, live in the same gated community, while Kris, Kim, and now Kylie Jenner all live about a mile away in Hidden Hills, California.
Kim and Rob have famously butted heads over the years. Some of their more memorable disputes include Rob leaving Kim's May 2014 wedding to Kanye West in Florence, Italy, and calling her the "b*tch from Gone Girl" in an Instagram post in January. For her part, Kim has referred to her brother's behavior as "pathetic," and accused Kris of babying her only son.
"You should not be paying for your son that is almost 30 years old to buy a house," Kim told Kris in an April episode of Keeping Up With the Kardashians.
Though Kris clapped back by calling out Kim on her short-lived marriage to NBA pro Kris Humphries.
"I've seen you guys through so much s**t that you, that I have to f**king put up with," Kris retorted. "'I'm married for 72 days.' Really, that's normal?"
