The dad-to-be shared a photo of Chyna eyeing an enormous plate of food with a smile on her face and her baby bump on full display.
“I think both of my girls are happy now,” Kardashian captioned the snap, referring to his fiancée and their baby girl, who is due in just four weeks.
The 28-year-old reality star took to Snapchat to reveal that she had recently gained weight — after losing about 7 lbs. last month — while pregnant with her second child, taking her total gain to over 50 pounds. However, her goal was much higher.
“Like no lie, my goal is to gain 100 lbs. this pregnancy,” she admitted in a Snapchat video in June. “I’mma tear it up, and then I’mma snap back.”
Kardashian, 29, is also ready to lose weight once the baby is born. He put together a side-by-side of him and Chyna on Instagram, showing a photo of Kardashian from a few years ago, prior to his weight gain, and a photo of Chyna from before her pregnancy.
“Oh yeah we snapping back lol,” he wrote. “Baby will be here in 4 weeks and I’m done with carrying this pregnancy weight. Me and my baby gonna be right. MOTIVATION TIME! We almost there Chy. F— Chy looks so bomb here aghhh!”
Last month, a source told PEOPLE Kardashian is “extremely bothered by his weight gain.”
“It’s not like he let himself gain weight because he doesn’t care,” said the insider. “He just hasn’t been able to mentally motivate himself to do something about it. It’s like an evil circle — the more he gains weight, the worse he feels mentally.”
‘Rob is a great guy,” added the source. “His struggles are very sad. It seems they could be fixed with help.”
