The 21-year-old model took to social media bright and early to reveal her boyfriend had gifted her with a customized Aston Martin DB11 which costs upwards of $250,000.  

The world's youngest billionaire styled her dark tresses out straight and appeared in very high spirits as she ran out from the plane to Sofia's car to wish the birthday girl in person. 

Sofia videoed the makeup mogul and posted in on her social media. It's now been deleted.

'Wow wow wow [sic] best bf award,' she wrote as she opening the door. 

Sofia's smooth new drive was all orange from the inside, including the steering wheel, dashboard and glove compartments. 

And while her new car is something many won't even get to test drive in their lifetime, that wasn't the only car she received on Saturday. 

While she didn't detail who had given it to her, she shared that she had also received a new Range Rover.

Sofia and Scott have been dating since September 2017 despite their 15 year age-gap. 

Scott and his ex Kourtney Kardashian split for good after more than ten years together in 2017, but they 'co-parent' their children Mason, Penelope, and Reign.
