Kourtney's younger sister, Kylie Jenner, 18, set up a profile on Bumble for the reality TV star, who split from her longtime partner and father of her three children, Scott Disick, last year.

Admitting she had taken 37-year-old Kourtney's phone, Kylie told fans on Snapchat: "I have Kourtney's phone, I know her password. Should I go through her text messages and read them to you guys?

"I think she's gonna kill me if I read her text messages, so I think I think I'm gonna set her up for Bumble. I think she needs to be on Bumble."

Kylie then set up the profile with a number of pictures and information on her sister's age and alma mater, the University of Arizona.

Explaining the situation to Kourtney later, she said: "I set you up for a dating profile. I just gotta take care of my big sister."

Kourtney, who has children Mason, six, Penelope, three and one-year-old Reign with Scott, has been single since their split, although she was linked to Justin Bieber, 22.

Meanwhile, despite his break-up with Kourtney, Scott is still close to the Kardashian/Jenner family and was spotted hanging out with Kourtney's sister Kendall Jenner, 20, and their mother Kris Jenner, 60, in Cannes this week.

A source said: "Scott is still very much around. He communicates with all the siblings, and he sees Kourtney a lot. He joins family dinners and is always invited for holidays. He's fun to be around. Plus, he's family."

Kourtney's family are said to be keen to remain on good terms with Scott for the sake of his and 37-year-old Kourtney's three children.

The insider added: "No matter what happens, he is their dad. The family will always care about Scott because of that. Think what you want about the Kardashians, but they don't shut people out."

While Kourtney's family have shown their support for Scott, the businessman - who checked himself into rehab last year - has previously been forced to defend his post-split partying.

He said: "The truth is I just to live my life and I want to have a little happiness and a little balance. I'm not doing drugs, I'm not doing anything insane, so I think people just need to relax ... I just want to try to live my life.

"I'm not sure I can stay home every single night at 32 years old and be sane. In the end, I'm trying to live my life. I'm trying to live it healthy. I'm trying to be there for the people I love, which is Kourtney and kids, but you know what, we're not together."
