Kylie Jenner and Blac Chyna: Tyga's Girlfriend and Ex Are Now Best Friends

Sworn enemies Kylie Jenner and Blac Chyna shared the camera while posing for a series of photos on their Snapchat accounts Thursday, inciting more questions about what exactly is going on between Tyga's girlfriend and Rob Kardashian's fiancee.

Out of nowhere on the afternoon of April 21, Jenner and Chyna both took to social media to reveal that they were having some quality girl time.

"When we’ve been best friends the whole time,” the 18-year-old Keeping Up with the Kardashians star wrote on Snapchat, along with a picture of them together.

 Chyna also posted a hilarious face-swap of herself and Jenner and wrote on another mirror pic of the gals: “Hanging out with my lil sis.” Both stars were all smiles and looked close in their series of snaps. It sounds like Jenner and Chyna have finally put their differences behind them.

Rumors swirled that there was bad blood between Jenner and Chyna after a series of crazy family connections intertwined their lives.

The pair have a complicated history together. Chyna shares a son with Jenner's boyfriend Tyga, to whom she was once engaged. She is now engaged to Jenner's brother Rob, and is also best friends with Amber Rose, the ex of Rob's sister Kim Kardashian West's husband Kanye West.

Even more questions arose when Jenner stayed silent on social media after her brother’s engagement, while she was quick to congratulate other family members on their big days. Kim, Kourtney and Khloé Kardashian and Kris and Kendall Jenner have yet to comment on Rob’s happy news.
