Rob Kardashian, Blac Chyna Fuel Romance Rumors By Working Out Together; Are The Two Just Fitness Buddies?

Are Rob Kardashian and Blac Chyna soul mates or just swole mates? According to reports, the two, who have been rumored to be dating, have been spending a lot of time together — and a majority of it has been in the gym.

TMZ revealed that Chyna, 27, has acted as a “positive influence” on Kris Jenner’s eldest son, helping the 28-year-old get back in shape for the new year. Rob has had an ongoing battle with his weight. In 2013, the reality star opened up about his health struggle during an episode of “Keeping Up With the Kardashians.”

“I was at my best health at 26, and now I have numbers that are freaking my whole family out,” he previously stated.

Well, it looks like Rob is attempting to get those numbers back down — and it’s all thanks to a little help from Blac Chyna.

It was reported that the video vixen, who has a 3-year-old son with Kylie Jenner’s rapper beau Tyga, introduced Rob to her personal trainer in December. TMZ states that since then, the two have partaken in “several intense workouts together” in an attempt to reach their fitness goals.

But it looks like burpees are the least of Rob and Blac Chyna’s problems. People magazine reported that Rob’s younger sister Kylie, 18, is “livid” that Rob has been romantically linked to her boyfriend’s ex. On Monday, Tyga’s, 26, baby mama shared an image of herself with Rob's tattooed arm around her.

“The beginning,” she captioned the photo.

The image received more than 100,000 likes — but it doesn't seem likely that Kylie double tapped the photo.

"She feels super betrayed and can't understand why someone in her own family would stab her in the back like that,” a source divulged to People magazine.
