Watch Kylie Jenner Give Travis Scott a Tattoo at His Extravagant Birthday Party

Kylie Jenner went all out for Travis Scott's birthday. The rapper turned 28 last Tuesday, but his presents from Kylie came a bit earlier.

In a gigantic display of affection, Kylie bought a billboard in Los Angeles last week, featuring a close-up photo of the her and Travis' 14-month-old daughter Stormi, along with an adorable picture of the makeup mogul and the baby girl posing together. “Happy birthday daddy,” the massive the billboard read. “Love, Mommy & Stormi xo.”

But the billboard was just the beginning. On Travis' actual birthday, Kylie threw him a party at the Universal Studios lot in Los Angeles. The party's theme was inspired by a gas station, featuring custom merchandise, a Cactus Jack shoe cake, and a Slurpee machine.

The party, which was attended by Kylie's sisters Kim Kardashian and Kendall Jenner, also included a tattoo station. Travis, who has plenty of tattoos, didn't pass up on the chance of adding more ink to his body. And we're sure he was pretty happy with his tattoo artist: his own girlfriend.

On Saturday, celebrity tattoo artist JonBoy shared a video of the Kylie wearing rubber gloves and leaning over Scott’s arm with a tattoo needle.

Outside of the ink Jenner gave him, the Houston-based rapper got other tattoos as well. Kylie also got some ink of her own, but it has yet to be revealed.

The power couple appears to be at a great spot in their relationship, so much so that they're thinking about adding a new member to the family. In another birthday tribute, Kylie shared an Instagram post dedicated to Travis, closing the post's caption with, "Let’s f**k around and have another baby."

We can't wait to see Kylie and Travis' relationship continue to grow.
