A photo posted by ROBERT KARDASHIAN (@robkardashian) on

The plot thickens. Rob Kardashian shared a photo of Blac Chyna on Instagram on Wednesday, January 27 — and she looks just like his older sister, Kim Kardashian. The reclusive Arthur George sock designer, 28, captioned the photo with DJ Khaled’s beloved key emoji, which the rapper uses on social media to express his "major keys to success."

The snap is a close-up of Chyna, 27, looking innocent in the sunlight sans makeup. Chyna — who used to be friends with Kim — has a pout similar to Kim’s in the pic.

Rob’s post comes after the makeup artist shared Snapchats of herself seemingly working out with the Dancing With the Stars season 13 contestant. In the 10-second videos, a voice that sounds a lot like Rob’s can be heard cheering on Chyna during their workout. 

Us Weekly previously confirmed that the duo have been seeing each other for the past two weeks. “There’s a romantic vibe there,” an insider told Us of the unlikely couple.

That said, the Kardashians are torn about being supportive of his new relationship, given that Blac Chyna is the ex-fiancée of Kylie Jenner’s boyfriend, Tyga.

"The family is in a bind, trying to be supportive of Rob's life while being sensitive of Kylie's relationship with Tyga,” another source explained to Us.
