Rob Kardashian is ecstatic to hear Blac Chyna and Kylie Jenner have called a truce.
"So happy my girls finally got to talk and make peace! #MyFamily #AllLove," he captioned a picture of his 27-year-old bride-to-be with his 18-year-old sibling.
Blac Chyna and Jenner shocked fans by cozying up for the photos Thursday.
Blac Chyna captioned one post, "Hanging out with my lil sis," while Jenner wrote, "When we've been best friends the whole time."
Jenner's boyfriend, rapper Tyga, was previously engaged to Blac Chyna.The former couple share 3-year-old son King Cairo Stevenson, and Jenner and Blac Chyna had bad blood for a time because of the complicated dynamic.
Sources told TMZ the truce was arranged by Kardashian and Jenner's sister Kim Kardashian, who reached out to Blac Chyna several weeks ago.
Insiders previously told E! News Jenner was "infuriated" by Blac Chyna dating her brother and planned to ignore the model's "antics."
Blac Chyna and Rob Kardashian were first linked in January and got engaged earlier this month.
Rob Kardashian's mom and other sisters have yet to explicitly address his engagement.
The reality star proposed to Blac Chyna with a $325,000 7-carat engagement ring and bought the model a $200,000 Lamborghini this week.
