The 28-year-old reality star is just weeks away from welcoming her and her fiancée Rob Kardashian's first child together, but it seems Chyna can't wait to shed her pregnancy weight as she took to Instagram on Sunday night (06.11.16) to share a photo of herself before she was pregnant.

The photo sees Chyna sitting naked on a bed showing off her sexy and booytlicious figure and was simply captioned: "Soon."

And she's not the only one who wants to get rid of their pregnancy weight, as her fiancé Rob, 29, previously joked that he too needed to lose the weight he'd gained recently.

The father-to-be shared a picture of him and his beau - who flaunted her pre-body frame in a skimpy blue printed bikini - to his Instagram account, which he captioned: "Oh yeah we snapping back lol ... baby will be here in 4 weeks and I'm done with carrying this pregnancy weight me and my baby gonna be righttttttt ,,, MOTIVATION TIME‼ we almost there Chy F******K Chy looks so bomb here aghhhh (sic)"

The 'Rob & Chyna' stars plan to follow a "strict" diet once their baby is born later this month, and Chyna - who already has four-year-old son King Cairo with her former partner Tyga who is dating Rob's half-sister Kylie Jenner - claimed she plans to undergo rigorous "waist training" to get her pre-baby body back.

She said previously: "My goal is to gain, like, 100 pounds this pregnancy. I'm gonna tear it up, then I'm gonna snap back. Strict diet, waist training, detox tea and working out."
