So 'Unstable!' Rob Dumps Pregnant Blac Chyna Amid Cheating Scandal

Will Rob Kardashian ever get it together?
On last night's episode of Keeping Up with the Kardashians, the reclusive daddy-to-be cruelly ditched his grandmother's birthday party — and his baby mama Blac Chyna — for a wild trip to Las Vegas, leaving his fiancee and entire family devastated.
Though he initially agreed to make the trip to San Diego for Kris Jenner's mother M.J. Shannon's bash, he began complaining that he had nothing to wear due to his huge weight gain.
But when sisters Khloe and Kim sent a pro stylist to dress him up, the unemployed 29-year-old remained wishy washy.
"His complaint is he has no clothes. Now that he has options of clothes to wear, he's not willing to try anything on!" Khloe sighed to the cameras.
In a bizarre twist, Kim and Scott Disick discovered that Rob deleted all photos of Chyna from his social media page.
"I know that Rob and Chyna have an unstable relationship," Kim said. "There is obviously two sides to every story."
So Kim and Scott called up Chyna, who explained that Rob threw a hissy fit when she disagreed with a business decision.
Chyna believed that Rob picked a fight with her just to avoid going to his grandmother's party.
"I just think that Rob has to start being honest. Stop the excuses!" Kim huffed. "That's what pisses me off. If you don't wanna come, don't come!"
After the successful party — who Chyna attended alone — the sisters fumed over their brother's immature behavior, which included blocking his baby mama and entire clan from calling or texting.
"It's crazy how he's acting. It's so f***ed up!" Khloe told Kim and Kourtney.
"Rob is going to be a dad, and he has a family to answer to," the more even-keeled Kim said. "He has to deal with his problems, he just can't run away and ignore them."
Though the family blamed Rob's behavior on his insecurities, obviously there was much more going on in his relationship with Chyna.
As RadarOnline.com exclusively reported, she was caught kissing hunky actor Pilot Jones earlier this year— possibly around the time she conceived her unborn baby!
Meanwhile, Scott decided to resurrect his "Lord" persona at Khloe and Kim's urging.
But he took it too far when he flew to London on a whim and bought a new plane.
"I'll obviously put Lord on the side," he boasted. "Nothing pretentious, you know?"
And Kim learned how to style her biracial daughter's curly hair.
"I thought it would be so much easier to learn!" she complained at a hair tutorial.
But by the end, she mastered two French braids in 3-year-old North's hair.
Will Rob and Chyna make it to their baby's birth? Sound off in the comments.
