'Keeping Up with the Kardashians' episodes might soon witness the clash of sisters Kim Kardashian and Kendall Jenner for the latter allegedly believes that she is better than everyone else.

Latest media reports suggest that Kendall's sudden recognition as model contributed to her changed character. Hollywood Life reports that the young Jenner has an "ego problem" which makes her believe that she is much superior than her older sister, Kim Kardashian.

For this reason, Kendall is allegedly asking E! to make her paycheck bigger than her sister's. Recently, Kendall posted an Instagram photo of herself with Kim looking up to her face. The photo's caption read: "She looks up to ME #BalmainArmy"

"She (Kendall) thinks she's the hottest sister by far. Now that she's famous and heavily involved in fashion, she sees herself as better than everyone else. She has become an egomaniac. That she's now demanding twice as much as her sisters to film the show," claimed an insider to Ok! magazine.

Another factor that might contribute to the sisters' alleged feud is FHM's list of Sexiest Women wherein Kim placed 38^th while her sister came in at 31^st.

Several media agencies have reported that Kendall was making fun of her half-sister's height. Despite her young age, Kendall was able to land several projects with fashion magazines and runway shows.

She similarly had the opportunity to host Canda's MuchMusic awards with her younger sister, Kylie. Recently, the sisters also penned a novel titled "Rebels - City of Indra." Reports are circulating that momager Kris Jenner is determined to have the book adapted into a movie.
