Rob Kardashian's fiancée Blac Chyna highlights pregnant belly

She said on Sunday during a Snapchat session that she wants to 'gain like 100lbs in this pregnancy.'

But later that night Blac Chyna looked like she's still fairly slender.

The 28-year-old fiancée of Rob Kardashian showed off her little pregnant belly in a snug zip-up jacket as she walked to her SUV outside Busby's in Hollywood past midnight. The model also flashed her sizable backside.

The ex of rapper Tyga (who she has son Cairo with) also had on a very tight pair of semi sheer black workout leggings that left little to the imagination.

The future daughter in law of Kris Jenner, 60, also wore jazzy slides that showed off her foot tattoo and she wore a red wig.

Long, pointy green nails made her look ready for Halloween

The former best friend of Kim Kardashian held onto a smart phone in one hand and also had a bag on her arm, which was from Kendras Boutique.

She was also seen walking behind a handsome man.

He had on a grey sweatshirt and a red cap.
