It seems Kris Jenner’s boyfriend, Corey Gamble, spends a lot of time with Kourtney Kardashian.  Meanwhile, Kim and Khloe are reportedly upset about it.

Kourtney Kardashian is showing off her new diva-like behavior by indulging in a “weird” relationship with her mother’s younger boyfriend. She has also been interfering with Rob Kardashian’s new house, says People.

Kim and Khloe just cannot get over the issue of how much time she spends changing out with her mom’s boyfriend, Corey. On the May 15 episode of “Keeping Up With The Kardashians,” Kim and Khloe confronted her about all the time she’s spending with Corey.

On camera, Kim stated that their relationship is a “little weird,” while she described the dynamic as “bizarre.” She also complained about the “inappropriate” family hike the two went on.

“I FaceTime him literally every day!” Kourtney replied when she was questioned.

Kris’ young boyfriend Corey is adapting pretty well into the Kardashian lifestyle. He has been settling in so nicely that family members think it’s a bit strange how close he is to the 37-year-old.

Khloe said that she loves Corey and finds him “super nice.” However, she never asked him to hang out. Thirty-one-year-old Khloé tells the cameras that Kourtney and Corey are like “conjoined twins.”

Kim also told Kris that Kourtney is becoming the new diva.

While she tried to confront Kourtney about her relationship with Corey, Kim made a confession of not knowing her pseudo stepdad well enough, says US Magazine.

“I don’t even know where he’s from,” Kim said. “Like, does he have sisters?”

According to People, Kim and Corey ended up bonding up a storm.

Slowly, Kim started getting amused with Corey. She said that it is a blessing to my mom to find someone, who could just fit in so well. She also said that Corey is a cool guy and “goes with the flow.”
