Say hello to Bumble’s newest member -- Kourtney Kardashian!

In a series of Snapchats on Friday, Kylie Jenner revealed that she stole Kourtney's phone and signed her oldest sister up for the popular dating app.

"I think [Kourtney's] gonna kill me if I read her text messages, so I think I’m gonna sign her up for Bumble," Kylie quipped in one of the Snapchat videos. "I think she needs to be on Bumble."

The oldest Kardashian sister has been single since splitting from her longtime on-and-off-boyfriend, Scott Disick, in July 2015. 

Kourtney, 37, did have a problem with Kylie's sneaky move, but it wasn't for the reason you're probably expecting. "These are the photos you pick?" the mom-of-three asked as she flipped through the profile, which even included that she graduated with a Bachelor's Degree in Theatre Arts and a minor in Spanish from the University of Arizona.

The 18-year-old reality star assured Kourtney that dating apps are a totally "normal" thing to be on these days. "Like, everybody's doing it. I think it's cute," Kylie explained in another snap. "But girls make the first move, so you can make the first move."

At least the Kylie Lip Kit creator had a very good reason for signing Kourtney up for a dating site without telling her -- she just had to "take care of her big sister." OK, that's sweet!

Maybe Kylie will be making a profile for herself as well? The youngest Jenner sister recently split from Tyga and is rumored to be dating another rapper, PartyNextDoor. Find out more in the video below.
