Clearly, all of those intense workouts have paid off!

Kardashian and Chyna dined at the Mexican restaurant with four friends but left separately. An eyewitness tells ET that Kardashian left through the front door around 11 p.m., while the pregnant model "snuck out back" by herself. Their friends that met up with them exited in an Uber.

A lot has certainly changed for the Kardashian clan since Rob, 29, proposed to the 28-year-old model in April and failed to inform Khloe -- or any members of his famous family -- about the engagement.

Last month, the recently engaged couple proved there was no bad blood with the rest of the Kardashian-Jenner clan, however, when they attended Khloe's 32nd birthday bash at Dave & Busters in Los Angeles. The parents-to-be were all smiles at the celebration, even posing for Snapchat selfies with Kim Kardashian and Kris and Kylie Jenner.

Khloe hopped in on the action as well, utilizing the venue's photo booth. In one shot, both Rob's sister and fiancée kissed his cheeks as he flashed an adorable smile. Hear more in the video below.
