Fans all know that Kylie Jenner and Tyga have been dating for some time, although they have said they are "just friends" when asked.

Well, the rumors have been confirmed, and one of the most talked about Hollywood couples has gone public for the first time!

Tyga posted a photo of his girlfriend for her 18th birthday. The "Rack City" rapper called Kylie the "dopest girl ever" in the Instagram post of her dripping soaking wet with a skin tight dress on.

Then he bought her a Ferrari for her birthday, amidst rumors that Tyga previously gave her an old car that he had taken back from his ex-girlfriend Blac Chyna. This car is brand spanking new, and he surprised her with it at her birthday party amongst friends and family members.

But the real news is when the couple, dubbed Kyga, went on vacation to Mexico and packed on the PDA. Fans could see photos of them together on their official page, holding hands, touching, and Kylie sitting on his lap.

In one Instagram post, the 18-year-old is holding her rapper boyfriend's hand while they take a stroll together.

We could assume that they definitely went public when he came to her birthday party with a Ferrari. The car costs $320,000, according to PEOPLE. Most people would not drop that kind of cash on an acquaintance.

And who could forget the time when Khloé Kardashian finally opened up about her baby sister, then 17 years old, dating a 25-year-old father?

"Kylie is taking business meetings and bought her first house, or she's going on a private plane with Karl Lagerfeld to take a meeting," Khloé said in July. "That's not even what people do in their 30s. It's a rare circumstance, so let's treat this as a special case."

We all knew they were together. But now we really know. Let's assume that they are public now because Kylie is finally of age.
