Twerk Off! Amber Rose/Blac Chyna vs. Natalie Nunn/Sarah Oliver Amid Chris Brown Dating Rumors [WATCH]: Pregnant 'Bad Girls Club' Baby Bump Mocks Nicki Minaj Booty-Shaking VIDEOS

Earlier this week, infamous Hollywood socialites Amber Rose and Blac Chyna indulged in a major nightclub twerk-off... and fans went completely insane. The videos were initially posted on The Shade Room's Instagram and quickly went viral online:

Rose also shared some "girlfriend bonding" on her own Instagram:

Oh, and The PinkPrint beauty Nicki Minaj recently had some sexy booty-shaking fun, too:

Woah.

But then former "Bad Girls Club" rebel Natalie Nunn decided to shake her buns, and some fans were not so enthused. Probably because the reality show bada$$ is four months pregnant with her first child!

Apparently, the clips have since been removed. But according to Bossip.com, Nunn and fellow "Bad Girl" Sarah Oliver attempted to mock the bootylicious move (a favorite among the celebs). Nunn, dressed in PJs and a head wrap, "got down on all fours" and popped her derriere alongside Oliver. Several followers then blasted the soon-to-be mommy, insisting that the footage was "inappropriate" for someone expecting a child in a just few months.

As MstarsNews previously reported, the Oxygen channel troublemaker recently announced that she's expecting with hubby Jacob Payne. The "Bridezillas" couple had their fair share of relationship ups-and-downs, been are very happy to now start a family together:

Oh, and given all the twerk mayhem, please enjoy this classic throwback:

Meanwhile, rumors suggest that Wiz Khalifa's ex is now dating Chris Brown, after the two were spotted provocatively dancing at LA's popular Supper Club. What's up with all the raunchy twerking!? Were they just having some innocent party fun?

Wonder what Karrueche Tran must think...

Nunn did remove the controversial videos, but she's still spending ample "sexy time" with her "Bad Girls" BFF:

Is this good behavior for a baby-bump flaunting diva?
