Chyna, 27, took to Snapchat and Instagram Wednesday to show off a brand new, bright purple Lamborghini gifted to her by Kardashian, 29.
"Thank you baby for my Huracan Lamborghini," she captioned a picture of the two posing alongside the sports car, which retails starting at $199,800.
"Yes! So happy!" she gushed in another video.
And that's not the only gift Kardashian has splurged on for Chyna recently: He proposed to her a little over two weeks ago with a sparkly 7-carat diamond ring, just 10 weeks after the two went public with their relationship.
And while a source recently told PEOPLE the two are "very excited" about wedding planning (and are even "talking about babies"), the engagement has been shrouded in drama as Kardashian's famous family has yet to publicly acknowledge the news. (Chyna has a long and complicated history with the Kardashian-Jenner women, stemming largely from the fact that she was previously engaged to and shares a son with Kylie Jenner's boyfriend Tyga.)
"The family is really not into the engagement," a source recently told PEOPLE. "Khloé [Kardashian] 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."
As far as they're concerned," said the source, "Blac Chyna will never be a Kardashian."
