Despite telling her Instagram followers she had an event she promised to make an appearance at months in advance, the Jenner sisters were reportedly furious Khloe refused to show up to their dad Caitlyn's 70th birthday bash, leaving the pair convinced she didn't front because of her strained relationship with the retired athlete.
As per the source, Kylie and Kendall didn't buy Khloe's excuse, claiming the Good American founder— who did send Caitlyn a bouquet of flowers on her big day— only thinks about what's best for her.
“She doesn’t seem to care about anybody else besides her,” the insider spilled. “Khloe doesn’t return calls, she gets drunk at parties and starts talking dirt about their dad and everyone else in the family. Plus, she’s late for meetings or doesn’t show up – and that reflects badly on everyone.”
Although her family rallied around her after Tristan Thompson cheated on Khloe while she was heavily pregnant and then with Kylie's best friend, Jordyn Woods, the insider says they're frustrated with her constantly changing her mind about where she stands with her cheating ex-boyfriend— who she shares daughter True Thompson with.
“Kendall and Kylie realize Khloe went through a hard time with Tristan, but they’re over her unless things change fast,” the insider promised.
