Scott Disick gifts Sofia Richie an Aston Martin for her 21st birthday

Happy 21st birthday, indeed.

Sofia Richie, who has been dating Scott Disick on-and-off since 2017, just became legally old enough to drink on Saturday and got a major birthday gift from her 36-year-old boyfriend — an Aston Martin.

“Holy Sh-t!” she wrote on her Instagram story of the luxury car decorated with a massive bow.

The model and daughter of music legend Lionel Richie, also posted a view from inside her new ride with the caption, “Wow wow wow Best bf award.”

In another snap, she showed a view from the wheel along with her birthday manicure, a pretty pink color with a “21” design, done by celebrity nail artist Chaun P. Richie.

Richie documented her birthday festivities which started out with a flower-adorned breakfast spread likely organized by Disick, followed by videos of her and a group of girlfriends, including Kylie Jenner, primping and hanging out on a private plane where typical 21-year-old girl antics — drinking and dancing — ensued.

The girl gang was headed to the Wynn in Las Vegas to keep the party going.
