Kylie Jenner and on-again boyfriend Tyga went to Six Flags Magic Mountain in Valencia on Sunday, and the casually-dressed couple got a bit of VIP treatment when they arrived at the theme park.

Tyga's son King Cairo was also there with the manny (or a really well-paid family friend), and despite the nearby wildfires and crazy heat, the couple seemed to have a blast at the park. Kylie later tweeted, "Just want to take a moment to thank the firefighters and their efforts to contain the #SandFire. You guys are true heroes 💙."

In other news, it's been reported that Kylie was considering quitting Keeping Up With the Kardashians. According to OK! Magazine, the teen reality queen is getting getting tired of cameras following her around everywhere -- and she wants out of the family’s reality show. “Kris sees Kylie as the new Kim,” a source told the mag. “And she’s convinced Kylie will be waving goodbye to millions of dollars if she walks. Kris can’t see that the more she fights Kylie over this, the more likely it is that she’ll quit.”

We're not sure whether there is actually any truth to that, but Kylie WOULD be a fool for leaving the show. Unless of course she got her own spinoff with Tyga, and/or made a sex tape...
