Kylie Jenner's latest Snapchat might be her best one yet!

The 18-year-old captured brother-in-law Kanye West and boyfriend Tyga giving an impromptu performance in a bathroom — and it was seriously sick!

The rappers serenaded Kylie and older sister Kim Kardashian with an a cappella version of the 38-year-old's hit song "N-ggas in Paris," and the lyrics were especially fitting for the location.

"Meet me in the bathroom stall," Kanye started, with Tyga finishing off the famous line with, "Show me why you deserve to have it all." Kim lip-synching in the background was just an added bonus.

"We are so lame," the youngest Kardashian sister said at the end of the clip.

The video was just one in a series of snaps featuring Kylie's famous family, including another where the temporarily blonde reality star asks older sister Kourtney Kardashian if she's the new Snapchat queen.

"I am going to f–king kill you if you take my Snapchat throne," she whispered in her ear jokingly.
