Tyga may be on his way out of the Kardashian-Jenner dating complex, but his ex, Blac Chyna, seems to be heading in. Twitter exploded this morning with rumors that the former stripper is dating Rob Kardashian after she posted a photo of herself nestled in the crook of a tattooed arm that looks like it belongs to the reclusive former reality star.

Further evidence that the two are getting friendly: last week, Rob posted a rare selfie showing off his hazel eyes, and Blac promptly liked the photo. And this past weekend, the Shade Room caught Kylie Jenner throwing some shade at her brother with a comment she posted to Instagram:

It's no secret that Blac has been coming for Kylie ever since Tyga left her for the then-underage reality star, but could she be taking her revenge this far? The Kardashian-Jenners are known to be crazy tight, so if this rumor is true, both Blac and Rob can expect to see some backlash from Kylie's older sisters before long.
As for Kylie and Tyga, sounds like the ride is over on their roller-coaster relationship after the latest round of cheating allegations. Catch up on their last "breakup" with BET Breaks, below:
