As she anxiously awaits the arrival of her new baby girl, Blac Chyna is ready to have her pre-baby body back!

Rob Kardashian's fiancée took to Instagram late Sunday night, sharing a sexy throwback photo featuring her naked figure on a bed. In the picture, Chyna made sure to cover her private parts, but left very little to the imagination.

"Soon," the 28-year-old captioned the curvaceous snap.

Meanwhile, the reality star has been embroiled in a shocking cheating scandal leading up to the birth of her baby.

As Breaking Celebrity News reported, Chyna was secretly hooking up with singer-actor Pilot Jones earlier this year, and an insider claimed to Breaking Celebrity News he's telling friends he will demand a DNA test from Kardashian's shamed wife-to-be.

Based on the timing of Jones's hookups with Chyna,an insider told Breaking Celebrity News, "it's possible" that he is the real dad, NOT reality TV heir Rob.

Of course, Chyna already subjected Kardashian to a DNA test for their reality show, Rob & Chyna, in an episode that aired just weeks after Breaking Celebrity News exposed her affair with Jones.

"I know it's Rob's child, I've only been with him since we started dating," she insisted to her confused pals in one scene, despite Breaking Celebrity News's photo proof that she had secretly hooked up with Jones behind Kardashian's back. "It's just to shut down the rumors on the internet saying it might be two other people," she claimed on the show.

But that's not all! "Pilot is telling friends that he will ask Chyna for a DNA test when the baby is born," the insider told Breaking Celebrity News. "He deserves to know the truth ."
