Kylie Jenner slammed by fans for ‘GRINDING’ on her mom Kris’ boyfriend Corey Gamble at concert in resurfaced video

They wrote: "Anybody else find it kinda weird that Kylie was acting sexy in front of Corey and allegedly even grinded on him?"

Others seemed to agree as a slew of comments followed pointing out the family's relationship dynamic.

One person wrote: "Everything this family does is hyper-sexualized and incest-like. It’s extremely disturbing the way the sisters grope each other any chance they get."

While a second user pondered over Corey's intentions, writing: "We need a history on Corey and what he's about. I've always found him super off putting and I haven't been able to figure out why."

A third added: "Corey creeps me out"

And a fourth chimed in: "I’ve always thought their relationship was a bit odd."

Others mentioned Kris' ex son-in-law Kanye West, who recently accused the business executive of cheating on the momager.

"Him being so close with Kylie and him being more around Kylie’s age than Kris definitely sets off red flags. Kanye knew it and saw it too. A broken clock is right twice a day. It’s icky," one said.

While another echoed the statement, writing: "Definitely. He is so sketchy. Even before Kanye said. I’m just glad he acknowledged it. Corey is a weirdo."

'WEIRD' BEHAVIOR

This is not the first time Corey's actions have been criticized when it comes to the Kardashian-Jenner's youngest sibling.

In a resurfaced clip from Keeping Up With the Kardashians, fans were concerned over Corey's behavior during an argument Kylie had with her older sister Kendall, 26.

During a heated disagreement between the girls over a dress, Corey was seen following Kylie around the house throughout the entire scene.

One user captioned: "This scene is still so wild to me, why was Corey following Kylie like a dog?"

"I think Cory is more of a handler than Kris' boyfriend," one guessed.

"This whole situation was really weird and uncomfortable to watch," a second agreed.

CHEATING ACCUSATIONS

The comments came after Corey was put on blast by Kanye, 44, who shared an article about him allegedly locking lips with another woman.

The post, which was quickly deleted, claimed that Kris' beau had been allegedly "cheating" on her with a supposed woman at a nightclub.

The rapper gushed about his former mother-in-law though and said: "I love Kris. This woman is a hero and she’s done what she’s had to do to protect her family and make sure they prosper even if it meant telling everyone not to listen to me.

"I respect her grind, her hustle, and her mind. Kris is one of the best to ever do it."

Kris, 66, didn't appear to be fazed by the accusations as the couple were seen just days later deplaning Kylie's private jet in Miami.

Corey and Kris began dating in August 2014, shortly after her relationship with Caitlyn Jenner ended after 20 years of marriage.
