18 Most Epic Kardashian-Jenner Feuds of All-Time

Rob Kardashian has made it clear that he's no fan of his sister Kim, whom he once compared to "the bitch from Gone Girl" on Instagram. Rob's sour grapes could be in part due to Kim publicly fat-shaming him, but this sibling strife certainly escalated when Rob bailed out on Kim's wedding to Kanye West in 2014.

Jon Hamm lamented the downfall of society for celebrating the "stupidity" of people like Kim Kardashian, referring to her as a "f*cking idiot." Kim called his remarks "careless," because she considers herself a successful business woman. Jon followed up by affirming that his critique was indeed "accurate."

Farrah Abraham has a penchant for picking fights with folks more famous than she, particularly after she saw how many headlines she made following her feud with Nicki Minaj. In fact, said feud led to a new beef with Kendall Jenner, who had sided with Nicki. Farrah then posted a meme to Instagram suggesting Ray J made the Kardashian-Jenner family famous by appearing in a sex tape with Kim. She tagged Kendall and included the hashtag #lifechoices.

Blac Chyna's ex-fiance and baby daddy Tyga reportedly dumped her for an underaged Kylie Jenner, and the two women have been at odds ever since. They've traded numerous jabs on social media, and Blac angered the whole family by getting romantic with Kylie's brother Rob.

This one gets a little complicated. Amber first claimed that Kanye West cheated on her with Kim Kardashian, and that the she would still be with the rapper if is wasn't for Kim. Fast forward a couple years to hear Amber dissing Kylie's relationship with Tyga, who as we learned left Blac Chyna (Amber's BFF) for the then 17-year-old. Khloe Kardashian defended her sister and went at it with Amber on Twitter. In February of 2016, however, Kim and Amber seemed to reconcile when both shared a pic of them together following a nasty Twitter war between Kanye, Wiz Khalifa and Amber.

Daniel Craig echoed fellow actor Jon Hamm's sentiments during an interview with GQ, in which he referred to the family as, here's that term again, "f*cking idiots." Family matriarch Kris Jenner demanded an apology, but we never heard one from the James Bond actor.

Brody Jenner, son of Kim's ex-stepdad Caitlyn, has never been a fan of the big-bootied reality star. A source close to Brody has said he thinks she is "beyond fake and wants nothing to do with her." Brody was also reportedly peeved that his girlfriend Kaitlynn Carter did not receive an invitation to Kim's wedding to Kanye West.

This may be one you weren't aware of. However, Sharon Osbourne has reportedly taken many digs at the Kardashian family, criticizing Kim's baby's wardrobe and saying the Kardashian fame was built on nothing but beauty. Additionally, after hearing that Khloe Kardashian might replace her on Fashion Police, Kelly Osbourne complained that the Kocktails with Khloe host "knows nothing about fashion."

This one isn't a shocker, I mean, couples divorce for a reason. Theirs reportedly stems from a lack of communication about Caitlyn's transition to womanhood. Kris said she was blindsided by the ordeal and suffered a meltdown because of it. However, the two seem to be on somewhat better terms; Kris has since appeared on Caitlyn's new reality show I Am Cait.

Joan Rivers made a career as an insult comic, and the Kardashians gave her plenty of material over the years. However, when the Fashion Police host called Kim's infant daughter ugly, it was a new low. Joan didn't stop there, however. She spoofed the Kim-Ray J sex tape scandal with none other than Ray J himself. This led to Khloe canceling a scheduled appearance on Fashion Police in support of her sister, and Kim refused to sit next to Joan during the NBC Upfronts.

This sibling rivalry was said to escalate after Kim gave birth to Saint and Kylie was too busy partying in Miami to care. But the tiff reportedly started shortly after Kylie received lip injections. Kim was not happy about Kylie's decision, and others said Kim was becoming jealous of her little sister as her popularity increased.

Kourtney Kardashian and then-boyfriend Scott Disick purchased a home from former NFL star Keyshawn Johnson, but the couple claimed he left them saddled with a black mold problem. Kourt also accused Keyshawn of painting over the mold to conceal it, but he denied any wrongdoing and complained that Kourtney and Scott bothered him with 10 calls per day after the deal closed.

After Kylie Instagrammed a selfie in which she rocked cornrow braids, teen activist Amandla Stenberg accused her of appropriating black culture while doing nothing to help black Americans. Kylie shot back with, "@amandlastenberg Mad if I don't, Mad if I do…. Go hang w Jaden or something." Both girls were rumored to date Jaden Smith, so there may have been some underlying tension brewing.

This one may be a tad far-fetched, but the half-sisters were rumored to be squabbling during their parents divorce, with each taking a side in the split. Insiders also hinted that Kim was jealous of Kendall's modeling career, afraid of being unseated as the "hottest" sister.

Khloe inexplicably posted a nude photo that she thought to be Chloe following remarks the latter made about her family. Moretz won this one handily: She pointed out that Khloe was gross for posting revenge porn ... and that the girl in the pic wasn't even her!

Blac Chyna versus everyone, really, but these two have broken up and we're guessing that some kind of custody battle is in their future.

The ultimate celebrity feud... maybe EVER! In June of 2016, Kim exposed Swift as a liar, airing a recorded call between Taylor and Kanye West in which the former approved of lyrics the latter wanted to rap about her; after having previously told the world she was blindsided by Kanye's diss track.
