Blac Chyna Sparks Rob Kardashian Romance Rumors With Intimate Pic

The model captioned the photo: "The beginning."

Rob Kardashian appears to be getting rather close to Blac Chyna, who is Tyga's ex-girlfriend and the mother of his 3-year-old son, King.

On Monday morning, the 27-year-old model Instagrammed a photo of her in the arms of a man with tattoos identical to that of the 28-year-old reality star. "The beginning," she captioned the image.

This rumored relationship could cause some drama among the Kardashian-Jenner clan as Kylie Jenner has been in an on and off-again relationship with Tyga. Rob and Blac Chyna have known each other for years, but stopped being friends once things started to get serious between Kylie and the 26-year-old rapper.

After Blac Chyna posted the intimate pic, Khloe Kardashian took to Twitter to share a cryptic message. "You can do anything. But never go against the family," she tweeted.

After the tweet sparked speculation that she was referring to Rob, Khloe clarified, writing: ""You guys do know I have about 100 family members correct? I was referring to a family member who just bailed out of doing my talk show today."

She then added: "But hey, maybe my quote can go towards a few people today."

While Rob has been quite reclusive over the past few years, he does appear to be coming out of his shell a bit. Last week he shared a rare selfie, and according to his mom, Kris Jenner, he hopes to return to the family's hit reality show, Keeping Up With the Kardashians.

"He's still part of the show, he's had a year where he kinda wanted to chill,” Kris said earlier this month. “He hasn't been feeling well -- we didn't really know why -- he was just diagnosed with diabetes. So, we're taking care of that."
