AceShowbiz - It's good to know that Kylie Jenner and Corey Gamble get along well, but they might have got a little too close for comfort during their recent outing. The 22-year-old reality TV star and her mother Kris Jenner's boyfriend partied together this past weekend.

In an Instagram Story video shared by the makeup mogul, she was seen grinding casually to 38-year-old Corey. The two appeared to be enjoying the music at a J Balvin concert in Los Angeles on Saturday night, October 26. When another companion filmed Kylie and Corey, the two started rubbing their shoulders to each other's while dancing.

In another video, Kylie got risque with a female pal, who ground on the mother of one, while the "Keeping Up with the Kardashians" star jokingly slapped her friend's butt.

Kylie and Corey were joined by Scott Disick's girlfriend Sofia Richie, lash extension guru Yris Palmer, assistant Victoria Villarroel and other pals at the concert. Kris and Scott, meanwhile, were nowhere to be seen with the group in the videos.

While Kylie and Corey have a very good relationship, things recently got awkward between the tour manager and Kris' other daughter Kourtney Kardashian. Corey clashed with Kourtney and her ex Scott after Kris' boyfriend threatened to smack Penelope to discipline her.

"If your kid scratched me in the face, you don't think they deserve to be popped?" he asked Kourtney on the reality TV show. "Not at all," Kourtney snapped. Corey insisted if Penelope bit him he'd give her "a spanking for sure," and that "whippin' is that discipline!", inflaming her father Scott who responded angrily and swore at Corey.

Kris tried to ease the situation, insisting Corey would never hurt Penelope. An angry Kourtney agreed, "Because he will never be with my kids alone and if he does that in front of any of us there will be a f**king issue!"

After the episode aired, Kourtney tweeted that re-watching the events gave her "anxiety." She added that Corey's comments were "NOT OK with me and never will be."
