Jenner, 18, stole her sister’s phone Friday and set up an account for the dating app Bumble – documenting it all on Snapchat.
“I have Kourtney’s phone. I have her password. Should I go threw her text messages and read them to your guys?” Jenner asked in one snap. In another, she opted to set Kardashian, 37, up with a Bumble profile instead – choosing some flattering photos for her sister.
“Hey Kourtney. I set you up for a dating profile,” she told her sister in another snap. “Everybody’s doing it. It’s cute.”
Kardashian wasn’t sure if she approved of the photos Jenner picked out, but the younger sister continued to sell her on the app, in which only women can initiate conversations.
“Girls make the first move. So you can make the fist move,” Jenner said, who later added, “I just got to take care of my big sister.”
Kardashian responded on her own Snapchat account, saying, “You guys, Kylie is crazy.”
Jenner is recently single after a breakup with longtime boyfriend, Tyga. Kardashian, who shares three children with Disick, has been linked with Justin Beiber, with multiple sources telling PEOPLE in April that the pair had been hooking up but that it was nothing serious.
“They have hooked up a few times, including recently. It happens in L.A,” a source said. “He has met her kids, but they don’t hook up around the kids. It’s on nights when she has help and is able to go out.”
