Kylie Jenner Rented Out Six Flags for Travis Scott's Birthday

Kylie Jenner knows how to throw a party. Latest evidence: For her "baby" Travis Scott's 25th birthday, she rented out an entire amusement park.

Because Travis had never been to Six Flags, Kylie decided to book the entire park for Travis and his friends to celebrate his big day.

Kylie documented the night on her Instagram Stories, showing off everything from the thrills of the rides to the epic birthday cake she commissioned for her guy.

Speaking of the cake: It was 100 percent amazing. The dessert itself was made in the shape of a giant, black and neon roller coaster. And riding the coaster? Travis, Kylie, and even baby Stormi.

"You know she's not passing the height rule," someone joked in a video showing off the little Stormi character on the cake. On the cake, the infant sits in Kylie's lap and it's adorable. In real life, of course, that would be all kinds of illegal and not something the new mom would ever attempt.

Kylie's sister, Kourtney Kardashian was also there for the big night and posted some Instagram stories of her own.

In one photo from her Instagram Story, Kylie referred to Travis as her "baby."

And, in a post from earlier in the day, Kylie also sparked a new round of engagement rumors with a video showing off some new bling on her left hand. While Kylie did sport a flashy diamond ring on her ring finger, she also wore a similar ring on her index finger, meaning there's a good chance this is more of a fashion statement than a relationship update.
