Kylie Jenner and Tyga can finally tell the haters to hush.

Jenner, who turned 18 on Monday, celebrated her official entry into adulthood on Sunday night, partying with her family, friends and 25-year-old boyfriend Tyga.

Though Jenner and Tyga's relationship has always been under fire due to the (slightly icky) age difference, the rapper didn't hesitate to publicly lavish Jenner with gifts and affection. On Friday, the reality star was spotted driving a red Mercedes Benz G-Wagon, which is reportedly a gift from Tyga and may even have originally belonged to his ex-girlfriend, Blac Chyna. But the rapper seriously upped the ante on Sunday when he surprised Jenner with a brand new white Ferrari.

The couple's relationship seems to be going strong in recent months, despite Blac Chyna posting screenshots of texts that she claimed were from Tyga asking to see their 2-year-old son and saying he wants to "be a family again." In fact, things are going so well Tyga allegedly got a tattoo of Jenner's name and called her "the dopest girl ever" in a sexed-up birthday post.

Happy bday to the dopest girl ever!
