In fact, the model just proved those rumors to be true by giving a (very strange) tour of all the nutritious foods in Rob's pantry.
Chyna took over his Instagram on Friday, blowing up everyone's feeds by sharing a bunch of back-to-back videos that show all the organic, healthy foods he's stocked up on lately, including: quinoa, rain forest crackers, I Can't Believe It's Not Butter, fat-free sorbets, oatmeal and more.
However, being Blac Chyna and Rob Kardashian, of course it wasn't just your average, everyday tour of the pantry...Let's just say things got weird as f--k.
Throughout the entire series of videos, Chyna is heard continuously yelling, "What the f--k is this!?" and "Nah, man!" as Rob laughs in the background.
At one point, she shows a package of Irish steel-cut oats and comments, "I mean, I get his birthday is on St. Patrick's Day," before she begins yelling and laughing, "But what the f--k is this, brah?!"
She finally ends the whole thing with a video of herself pouting and saying, "It's just sometimes in life you have to eat healthy."
And that's exactly what the new couple has been doing. Recently, E! News learned that Rob has been working much harder, both in and out of the gym. His fitness routines are more consistent, and a source further explained that he's been "taking better care of himself since his health scare." Chyna is helping him continue along that path.
In fact, Rob showed off his progress when the he was spotted for the first time in a long time while out and about with his girlfriend in Los Angeles. He even shared an Instagram post Tuesday afternoon that read, "Progress = Happiness" after the photos surfaced.
On Thursday, he also allowed Chyna to post a photo of him smiling from ear-to-ear as she kissed his cheek in a Snapchat post.
We haven't seen the reality star this happy in a long time!
