Blac Chyna and Kylie Jenner are...best friends?

Jenner is dating rapper Tyga, who also happens to be Chyna's ex and father to her son, King. But that's not the only way the two are connected -- Chyna is engaged to Jenner's half-brother, Rob Kardashian. Chyna is also best friends with Amber Rose, who is also Kanye West's ex. And as we all know, West is married to Jenner's half-sister, Kim Kardashian. Many onlookers assumed that this would be enough fuel to put Blac Chyna and Kylie Jenner at odds, but it seems that we had it all wrong.

"When we've been best friends the whole time," read a caption on Jenner's Snapchat, which featured a photo of the two women. Chyna also shared a photo of the two with some touching words. "Hanging out with my lil sis," it read. The two even tried out Snapchat's face-swap filter. True BFFs indeed.

However, everything might not be as peachy in the Kardashian-Jenner-Chyna clan as it may seem in the photos. Sources told People that the engagement between Blac Chyna and Rob Kardashian has caused "friction" and that Khloe Kardashian was "particularly upset."

"Khloé and Kylie think Chyna is desperate, thirsty and playing with Rob's head," said the source to People in March. "They're also concerned she is after his money and that she is dying to stay relevant and get back at Kylie by being with Rob."

Either way the newly engaged couple seem to be doing extremely well -- Rob recently bought his girl a brand new purple Huracan Lamborghini for her birthday. The luxury car is valued at $200,000. As for the rock on Chyna's finger -- it's a whopping seven carat diamond ring.
