Competing couples? Blac Chyna and Rob Kardashian show off Audi R8 convertible hours after Tyga presents Kylie with $200k Maybach Mercedes

Perhaps there's some sibling rivalry simmering in the Kardashian/Jenner household. 

On Saturday, Blac Chyna and Rob Kardashian decided to take to Snapchat to show off their Audi R8 convertible.

It just so happens that earlier in the day, Blac's ex-fiance Tyga presented girlfriend Kylie Jenner, her former love rival, with a flashy Mercedes Maybach.

Not to be outdone Blac shared a Snapchat of her sleek ride.

Kylie's brother Rob, 29, can be heard exclaiming as Blac Chyna, 28, operates the mechanical folding roof on the almost $170,000 car.

The next clip was shared through Rob's account, and showed his beloved getting ready to pull the V-10 powered super car out into traffic.

Blac Chyna appears to be enjoying her time behind the wheel, as she beams at the camera. She wore a tight elastic top for the excursion.

It doesn't appear to be a new car however as Blac flaunted an identical Audi on social media in September 2015. 

Earlier in the day, Tyga, 26, didn't let his oft -reported insolvency get in the way of a seriously bling birthday surprise for his teen girlfriend Kylie Jenner.

The rapper filmed as he presented the soon-to-be 19-year-old with a sparkling brand new Maybach Mercedes on Saturday morning.

The most basic model of the luxury vehicle starts at $190,000 with the price rapidly climbing based upon specifications.

Happy early birthday to me,' trilled Kylie on Snapchat as she showed off her new blue car.

She was seen being surprised with the gift by Tyga, who filmed as she gushed: 'Whaaaat?' then added with increasing excitement, 'I love you T!' 

Beep beep! The next clip was shared through Rob's account, and showed his beloved getting ready to pull the V-10 powered super car out into traffic

Tyga sang 'Happy birthday to you,' as Kylie exclaimed: 'Stop! T!'

'What is happening!' she squealed, 'Oh my goodness!'

But despite Kylie's excitement, it is unclear how Tyga can afford such a pricey gift.

Indeed despite initial claims that the high-spender had bought Kylie a Ferrari for her 18th birthday last August, it was later revealed that Tyga couldn't afford the pricey purchase and instead simply leased the sports car in Kylie's name.
