During her appearance at the Academy Museum Gala on October 19, Kylie Jenner referred to the event as "a very special sister night."

The founder of Kylie Cosmetics walked the red carpet while wearing a vintage gown by Thierry Mugler. She was accompanied by her sister, Kendall Jenner, who completed her ensemble by wearing a black Schiaparelli dress with a similar strappy silhouette, E! Online reported.

They can be seen walking hand in hand at the Los Angeles event, and Kylie posted a video clip of the two of them. In the footage, they comment on how, even though they had seen each other the day before, they would miss each other when they split ways.

In the past, Kylie, 27 years old, and Kendall, 29 years old, have not always been a family lovefest. Throughout the years, Kris Jenner's youngest daughters have been involved in several arguments that have tested their relationship.

“Their fights have been epic, even worse than anyone has seen on TV. It gets ugly, physical even, very down-and-dirty," an insider told Life & Style Magazine.

Although Kylie and Kendall are quite wealthy women, several of their disagreements have revealed that they have reverted to their younger selves.

“Usually, it’s rooted in jealousy — who their mom pays more attention to, who’s the most popular. They’ve fought over borrowing clothes," the source added.

On the other hand, the two have occasionally cut deeper. Kylie, the mother of Stormi, who is six years old, and Aire, who is two years old, is not above reprimanding Kendall for being the only member of the Kardashian-Jenner family who does not have her children.

“Kylie loves to hit below the belt with that; it’s a sore spot for Kendall and makes her feel like the black sheep of the family. They have both made each other cry many times," the tipster claimed.

However, as of late, the cast members of the Hulu show "The Kardashians" have been as close as thieves would be. According to the insider, Kylie and Kendall tried to restore their relationship.

They continue to argue because they are regular sisters, but they have become better at forgiving one another and moving on with their lives. At this point, they are pretty close.

The fact that the two individuals share their unusual experiences is fantastic for them to have in common. About her experience growing up on reality television and continuing to expose her private world to viewers, Kylie has stated that it is difficult to find people who understand your life. The fact that we can rely on one another has been of great significance because it is such an uncommon occurrence... with celebrity.

According to the source, Kendall is also present for Kylie's children. According to the insider who spoke to Life & Style Magazine, she is always keeping an eye on Stormi and Aire and is a huge fan of both of them.

Kendall and Kylie are content to spend time together without the presence of cameras even though they frequently combine their professional and personal lives, Harper's Bazaar reported.
