Kylie Jenner just dropped a few stacks on best friend Stassie Karanikolaou, buying her long-time confidante a beautiful diamond ring that the beauty has chosen to rock on her pinky finger.

While sharing a private booth at Friday night’s Los Angeles Clippers game along with Jenner’s assistant, Victoria Villarroel, and influencer Kelsey Calemine, Karanikolaou flaunted the gorgeous rock while thanking the makeup mogul in a social media post.

“@kyliejenner you shouldn’t have,” Stassie wrote as she panned her phone up to Kylie, who gave a wink to the camera.

Kylie, 22, also threw Stassie a weekend-long soiree to celebrate her 22nd birthday in June, which included pool parties, bottle service and a “Handmaid’s Tale”-themed party that sparked a major backlash online.
