Entertainment TV Kylie Jenner and Blac Chyna Pose for Snapchat: 'We've Been Best Friends the Whole Time' Kylie Jenner is dating Blac Chyna's ex Tyga By People Staff Published on April 21, 2016 06:00 PM Share Tweet Pin Email Photo: Kylie Jenner/SnapChat Feud? What feud? Kylie Jenner and Blac Chyna posed for a photograph, which Jenner shared on Snapchat Thursday, insisting that (despite what people may think): “When we’ve been best friends the whole time.” The snapchat is sure to turn heads as the pair have a complicated history together. Blac Chyna, 27, shares a son with Jenner’s boyfriend Tyga, to whom she was once engaged. Blac Chyna is now engaged to Jenner’s brother Rob Kardashian, and is also best friends with Amber Rose, the ex of Rob’s sister Kim Kardashian West‘s husband Kanye West. Blac Chyna captioned a photo of the two together, “Hanging out with my lil sis,” and in another snap the pair partook in a face swap. Sources have previously told PEOPLE the engagement has caused friction within the Kardashian-Jenner clan, with Jenner, 18, and sister Khloé Kardashian particularly upset. “Khloé and Kylie think Chyna is desperate, thirsty and playing with Rob’s head,” a source said 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.” The friendly photo comes one day after Rob, 29, gifted Blac Chyna a purple Huracan Lamborghini as an early birthday present. Rob proposed to his fiancée over two weeks ago with a 7-carat diamond engagement ring. The engagement came just 10 weeks after the two went public with their relationship.
