Rob Kardashian Wants Blac Chyna to Take His Last Name? [PHOTO]

Rob Kardashian had already upset his family by allegedly hooking up with Blac Chyna, but it seems like he's still not done hurting them just yet. The only son of Kris Jenner wants Tyga's baby mama to take on his famous last name!

Hollywood Life has learned that the 28-year-old reality star wants Chyna to use the Kardashian surname just to diss his family, especially older sister, Kim Kardashian West.

“Rob’s going for the jugular. While he loves Blac Chyna, he wants to stick it to his sisters, mainly Kim, in the worst way possible," the insider said. "That’s why he wants Blac to change her name to Blac Kardashian. Rob thinks it’s hilarious.”

Mrs. West is known for giving her brother some tough love and obviously it doesn't sit well with the Arthur George socks owner.

"Another reason why he wants Blac to be a Kardashian is because he wants her to give Kim a run for her money in the family’s business of fame," the source continued. "He thinks Blac’s much sexier than Kim, has a better body than Kim, and would crush her when it comes to her famous booty!”

With the help of his famous last name, Kardashian believes that he and Chyna can possibly be the biggest stars of the family.

“Rob’s realizing that he’s got just as much claim to the family’s empire and fame, and he wants to share that with his bae Blac, so that they can make a name for themselves and be the new breakout stars of the family.”

And just to make sure that nobody would forget that he's with Chyna, Kardashian recently posted a pic of her on his Instagram with a key emoji as his caption.
