Rob Kardashian is one big spender!

The sock-selling reality star has purchased a $200K car for his lady love Blac Chyna -- and both of them showed off his big purchase on their Instagrams on Wednesday afternoon.

In the photos, the twosome were wearing low-key ensembles -- and cuddling up to each other. Rob is pictured in a Yankees cap and black shirt. Chyna was all smiles in a fitted white shirt and cutesy red winter hat.

The newly engaged star presented his model fiancee the purple 2016 Huracan Lamborghini this morning and promptly had it taken away from her Los Angeles home on a tow truck to be customized.


If we had $200K to burn -- there is no way we'd spend it on a purple Lamborghini, but we aren't a Kardashian!

We guess that's her present for sending him a photo of her undercarriage?!
