Kim Kardashian: Upset Sister Hangs out With Paris Hilton?

Hollywood is a small world! Paris Hilton and Kendall and Kylie Jenner were all photographed on Saturday in Glendale, CA, playing a game of kick ball. What makes this super awkward is the longtime feud between Kim Kardashian and Paris Hilton, which has been well chronicled in the tabloids, so why were Kim's little sisters hanging out with the socialite?

Apparently, Chris Brown hosted a kick ball game for celebrities, called It For Charity. Not only did the Jenner sisters attend the event with Hilton, but also other stars like Christina Millian, Jamie Foxx, The Game, and Chris Brown were present.

For the charity game, Kendall Jenner decided on a sporty outfit of black leggings, a large jersey, and a white baseball cap. Kylie Jenner went a completely different route and wore an oversized jersey, short shorts, and black thigh-high stiletto boots. Unfortunately, there was no picture of Kylie trying to kick the ball in her high heels.

Kim Kardashian might be upset to see her younger sister Kendall photographed standing next to Paris Hilton, laughing. Especially after all the mean things Paris has said about Kim over the years. Even though Kardashian started out as Paris Hilton's assistant, the two were also close friends. However, the friendship was a bit one-sided, as Hilton was shady to Kim every chance she got.

Hilton would demand that Kardashian clean her closet before they hung out, and reprimanded her for speaking while she was talking. Back then, even Nichole Richie made fun of Kim for being, 'the girl who used to clean and organize Paris Hilton's closet,' and called her a 'hoe.'

Hilton also dissed the entire Kardashian family. At the height of the feud, Hilton said in an interview, 'I created Kim Kardashian, her whole family owes me life.' Even though Paris apologized a few years later and the feud was thought to be over, Paris recently retweeted an article about Kim, titled: Kim Kardashian Making it the Old-Fashioned Way; On Her Back. Hilton then tweeted that it was an accident and claimed her phone tweeted the article while it was in her purse.

Not only were Kendall and Kylie on the same team with Paris Hilton, but they were also around their brother-in-law's, Kanye West, ex girlfriend, Amber Rose. Amber Rose also had a problem with the reality star. Rose accused Kim Kardashian of cheating with Kanye while she was still dating him, and while Kardashian was together with Kris Humphries. Rose says she called Kim to tell her to stop, but the reality star never called her back. Now that West and Kardashian have recently married, it might have been an uncomfortable interaction between all the girls. No word if Kendall and Kylie avoided Rose or not.

Kim Kardashian has not confirmed that she is upset that her two sisters were photographed laughing and hanging out with Paris Hilton, but who could really blame the reality star if she was? However, Kendall and Kylie are both young, so maybe they didn't know how they should handle the situation, or maybe they just didn't care.
