We don't see the appeal of whooping it up till the wee hours of the morning with a bun in the oven!

Blac Chyna donned a red wig and workout clothes to party with friends at Busby's in LA last night, and she didn't leave to head home until 1am! Fiance Rob Kardashian didn't tag along on the outing, so he must have been home babysitting his soon-to-be-stepson King Cairo.

The pregnant former stripper's baby bump is growing by the day, and she hasn't been able to resist showing it off on Snapchat. The makeup guru revealed in one of her vids that her goal is to gain over 100lbs with this pregnancy! "My goal is to gain, like, 100 pounds this pregnancy. Emma tear it up, then Imma snap back," she declared on-camera. Her current weight is 165lbs, so she's on her way!

She might be having the time of her life, but the Kardashians are worried that Rob will go broke trying to spoil her like her ex Tyga did. "Rob wants to buy her a new car . . . She wants a brand-new house before their baby is born. His family wants him to slow down. They’re [thinking], ‘Is this really how you want to spend money when you’re about to have a family?'" a source dished to Page Six .

No wonder the controversial couple got their own reality show! This is ratings gold!
