Rob Kardashian hands Blac Chyna the keys to new supercar

Reality TV star Rob Kardashian has treated his bride-to-be Blac Chyna to a brand new purple Lamborghini.

Kim Kardashian's brother proposed to the model earlier this month (Apr16) after a whirlwind romance, presenting her with a huge seven-carat, round brilliant cut diamond, worth a stunning $325,000 .

Rob is continuing to shower his new love with lavish gifts and on Wednesday (20Apr16), Blac revealed she had been handed the keys to a speedy new sports car, valued at around $200,000 .

Blac took to Instagram.com to show off the purple supercar, posting a photo of the happy couple posing beside her new ride.

"Thank you baby for my Huracan Lamborghini @robkardashian," the 27-year-old captioned the shot.

Ironically, Blac is no stranger to receiving cars as gifts - her ex-fiance and baby daddy Tyga previously presented her with a Mercedes G-Wagon, but she had to hand back the keys to the vehicle following their split in 2014.

The rapper has since also dug deep to keep his new girlfriend, Rob's half-sister Kylie Jenner, happy - he surprised her with a white Ferrari for her 18th birthday last summer (15).

The Kardashian clan has still to publicly congratulate Rob and Blac on their engagement, which has reportedly caused a rift in the family due to Kylie's romance with Tyga.

However, Tyga, who shares three-year-old son King with his ex, wasted no time in sharing his joy at the news on social media after the proposal news broke on 5 April (16).

"Everybody deserves 2 be happy," the hip-hop star wrote on Twitter. "What some1 does for their happiness is not my concern, as long as it's not interfering wit my happiness. It makes me happy to see the mother of my son happy. My only concern in this situation is my son. I want him in happy environments. He's innocent in this. & I want him to feel as much love as possible."
