Last week, Rob popped the question to Chyna at their California home. While many assumed the Kardashian klan knew about the engagement, it was soon revealed that the family was on a ski vacation in Vail, Colo. during the major announcement.
“Khloé and Kylie think Chyna is desperate, thirsty and playing with Rob’s head. 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,” says the source.
Kylie – who’s currently dating rapper Tyga, Chyna’s ex-fiancé and father of her 3-year-old son King Cairo – stands at the center of the controversy. Last year big sister Khloé came to her defense when rumors spread that she’d stolen Tyga from Chyna while still a minor.
“As far as they’re concerned, Blac Chyna will never be a Kardashian,” the source added.
The ever-growing Kardashian plot continues to thicken.
