The rules of the social media prank are pretty simple: the prankster calls up their friends on FaceTime and records their confused reactions after immediately being told, "I'm busy right now, can I call you back?"
Jenner was enjoying her time in a bath when she got the call, exclaiming, "What? You just called me!" -- while Jamie, who's in her phone under a fox emoji, reacted in similar fashion. Hailey, who's listed as "Hail Stonez," suspected something was up, asking, "Is this, like, a thing?"
Timbaland and Luka Sabbat, meanwhile, were both left wondering whether they accidentally called her.
