According to People magazine, "KUWTK" youngster Kendall Jenner is currently dating 21-year-old aspiring rapper, Young Jinsu. Here's what an alleged insider explains about the blossoming romance:

"They're dating - it's been at least a few months. They've been getting closer recently, and they've been hanging out all the time... They have that spark right now - they're just really feeling each other. They're not putting it out there yet."

The duo met over the summer, and Jinsu "fell hard."

Apparently, Jenner will make her new relationship public following her 18th birthday on November 3rd.

The source continues, "[Jinsu]'s so sweet. He kind of reminds you of Chris Brown, but way more charming and really talented. He's been working with a lot of big-time producers and artists recently."

Jenner allegedly appears alongside Jinsu in this photo he recently posted on Instagram. The "romantic" pic was re-posted by Jenner's younger sister, Kylie:

But 17-year-old Jenner denies that she even has a boyfriend:

@KendallJenner: "enough with the rumors! I'm single, people."

FYI - Young Jinsu once dated Justin Bieber's ex, Jasmine Villegas.
