In his fiery Instagram tirade toward his ex-fiancée, Blac Chyna, on Wednesday, July 5, Rob Kardashian claimed that their recent Father's Day trip to Disneyland was totally "staged."

"… Yes I'm being petty with this woman is fakes like we all good on Father's Day and begged me to go and staged the paparazzi to be there," he wrote among other things. "I'm done with this woman thank God for God ! Showing me the light !"

Though their trip to Disneyland looked like a dream via social media, Rob and Chyna’s Father’s Day celebration at the theme park on Sunday, June 18, was anything but.

An insider previously told Life & Style that the former couple — who brought along their seven-month-old daughter, Dream — couldn’t shake their sour moods despite receiving VIP treatment.

“Rob and Chyna could not stop bickering as they made their way around Disney,” the witness said. “They were sniping at each other the entire time.”

Things took a turn for the worse when the pair got lunch at the park’s members-only Club 33, which has a strict dress code policy.

“The club’s dress code is no joke — flip-flops and cutoffs are not allowed. But Chyna strode into the main dining room wearing very short cutoffs,” the witness continued. “Other diners gasped, and staffers tried to tell Chyna she couldn’t eat there dressed that way, but management let it go.”

While Chyna “spent the whole meal texting” (even though Club 33 doesn’t allow cellphone use) and Rob joked that “they were only eating there because Club 33 serves alcohol,” their little girl was the only one who seemed to be enjoying herself.

“Dream,” said the witness, “was perfectly behaved!”

Rob and Chyna welcomed Dream last November, but called off their engagement after they got into a massive fight in late 2016. Despite their toxic past, they have made several attempts to fix their fractured relationship for the sake of their family.

“I’m in it for the long haul, so I feel like my advice [for anyone in a similar situation] is therapy, know each other’s family, calling each other’s moms,” Chyna told Cosmopolitan South Africa in March. "I know we love each other and we’re fighting for each other, and the people we surround ourselves with are rooting for us.”
