Rob Kardashian wants to be involved in his family's lives again.

In roughly four weeks, Rob Kardashian and his fiancée Blac Chyna will be welcome their first child together and the anticipation is mounting! Now, while these two are seemingly overjoyed to take on the new challenge, they’re also looking to make some big changes when their baby arrives….

Today (Oct. 19, 2016) Rob posted an older, slimmer photo of himself next to an older, slimmer photo of his pregnant partner. He captioned the photos with a rallying cry to get motivated lose some weight when he becomes a dad:

“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 righttttttt ,,, MOTIVATION TIME!! we almost there Chy…FAAAAACK Chy looks so bomb here.”

Between prepping to get health and becoming a first-time dad (Chyna already has a three-year-old son with Tyga, Kylie Jenner’s fella), Rob most definitely has a lot on his mind but according to his sis Khloé Kardashian, he’s handling the prospect of parenthood with ease.

“Rob is fine. He says he’s really fine and calm about it, but I was like, ‘It’s OK if you’re nervous!’” Khloé told Us Weekly recently. “I think anybody would be nervous.”

As for Chyna, according to TMZ, she’s already treating herself! The former model was spotted at a car dealership earlier today eyeing the 2016 Rolls-Royce Wraith, which has a starting price of about $300,000. No word on whether she signed on the dotted line quite yet.

Why wait to celebrate, right?!
