Rob Kardashian Congratulates Kylie Jenner on 'Paper' Cover: Peace Sign After Engagement News?

Rob Kardashian is reaching out to his little sister, Kylie Jenner, in a very public way, telling her how proud he is of the big achievement of making the cover of Paper. It looks like a peace sign after their long journey to being okay (since he's marrying her enemy, Blac Chyna).

On Saturday, the 29-year-old congratulated his youngest sister on her new Paper magazine cover, reposting an earlier image of Jenner celebrating with the magazine at the Coachella music festival.

"Congrats Sis," he wrote with the Instagram photo, adding a heart emoji.

The 18-year-old Keeping Up With The kardashians star dropped her brother out of her life after learning that he was dating Chyna. Jenner strongly believes that the former exotic performer is no good for her brother and she will just worsen Kardashian's already complicated life.

Tyga's on-and-off girlfriend and Chyna had been feuding for quite a long time and the youngest of the Kardashian-Jenner clan is not too happy for the latest hook-up of her brother. “ Kylie is livid with this whole engagement thing,” a source told Hollywood Life. .

TMZ reported the Kardashian-Jenner clan had no idea that Rob was planning to propose to Chyna. The site noted that Rob waited until his family was out of town on vacation to pop the question to Tyga's baby mama.

“She is convinced Blac Chyna has a hidden agenda and is using Rob,” the source said. “She’s stressed out about the whole thing and just wants her mom and Khloe to talk some sense into Rob. She thinks he has been brainwashed!”

Despite his family's dislike of their relationship, the Arthur George socks owner proved that he and Chyna are in it for the long haul.
