'Ecstatic' Blac Chyna Planning To Change Her Name To 'Angela Kardashian'

Look out Kardashian klan, Blac Chyna is ready to take on the family name!

According to PEOPLE magazine, Rob Kardashian's new fiancée is overjoyed to change her name, which she plans to do officially once they've wed.

"She's soon to be Angela Kardashian. She's ecstatic," a rep for the model told PEOPLE, referring to Blac Chyna's birth name, Angela White. "She was more than excited, she was thrilled, just super happy."

Unfortunately, Rob's famous family does not seem to be as thrilled about their upcoming nuptials.

As RadarOnline.com previously reported, 60-year-old matriarch Kris Jenner jetted out of Los Angeles on Sunday with all of her ladies in tow. Yes, that means ALL of them — Kim, 35, Kourtney, 37, and Khloe Kardashian, 31, as well as Kendall, 20, and Kylie Jenner, 18.

Since Rob's big news was announced, the entire family has remained mum on the subject.

"The real reason that Kris took all the girls on this 'surprise' getaway is because she needed to break the news to them that Rob was going to propose to Blac Chyna," a source told RadarOnline.com exclusively, adding, "Kris is actually very happy for her son but she knew that his sisters were going to lose their sh*t when they found out."

And evidently, they did lose it.

"Kim, Khloe and Kylie are without words," the insider told RadarOnline.com. "Honestly the only ones that are happy for him are Kourtney and Kendall because they have always stood behind their brother."

As RadarOnline.com previously reported, Blac Chyna, 27, is the baby mama to Kylie's 26-year-old bad-boy rapper boyfriend Tyga's son, King Cairo, 4.

Welcome to the family Blac Chyna! And good luck to you.
