Khloe Kardashian may have reportedly just dissed her brother Rob Kardashian on social media. The "Keeping Up With the Kardashians" star posted a cryptic message following recent news about Rob and Blac Chyna's alleged new relationship.

According to Mirror UK, fans suspected that Khloe may have indirectly dissed Rob when she quoted "The Godfather" on her Twitter post. Her tweet reportedly came amid recent news that her brother and Tyga's ex-girlfriend Blac Chyna, born Angela Renée White, are now a couple.

However, the reality TV star later denied that she was referring to Rob on her tweet. She posted a couple of messages telling readers that she was talking about another family member, who failed to appear on her new show "Kocktails with Khloe."

Kardashian also hinted on Twitter that she initially had no idea about Rob and Blac Chyna's romance. But thanks to Twitter, she now know what all her family members are doing.

Kardashian's tweets came after Blac Chyna posted a photo on Instagram on Monday, showing her cuddling to a tattooed man. She simply captioned the shot, "The beginning."

Blac Chyna didn't mention her companion's name. However, viewers immediately suspected that she was with Rob. Mirror UK claimed fans recognized his ink from Rob's left arm. The site also shared a photo comparison to show the similarities between Rob's tattoos with those on the arm of the man cuddling Blac Chyna.

Commentators also suspected that Blac Chyna is with Rob in the photo. Another Instagram user named rebelxyellx wrote, "Wow ... Why does she wanna be with rob ?? Why does she even want anything to do with that family ?? She is way to good ." Meanwhile, another user named justcoralia thought Rob and Blac Chyna are a "cute couple."

However, a source told Us Weekly that Blac Chyna and Rob are not exactly a couple yet since they just started seeing each other. The insider further told the publication that they have been hanging out, although it's still unclear whether they are officially boyfriend-girlfriend. The insider added that there's a certain "romantic vibe" between the pair. Rob and Blac Chyna have reportedly been "inseparable for the past ten days."

Rob's relationship with Blac Chyna supposedly came as a surprise, considering his family's history with the model. Rob's other sister Kim Kardashian-West was reportedly one of her close friends in the past. According to Us Weekly, their friendship ended in 2014 when Tyga split up with Blac Chyna and started going out with her step sister Kylie Jenner.
