Justin Bieber and Kourtney Kardashian's alleged hook ups have been 'on and off for some months now'

Justin Bieber and Kourtney Kardashian have allegedly been "hooking up on and off for some months now," a new report has claimed. The Sorry singer and The Keeping Up with the Kardashians star had sparked dating rumours after they were first spotted together in December 2015.

"They have hooked up a few times, including recently. It happens in LA," a source reportedly told People magazine. "He [Justin Bieber] 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."

"Kourtney is great. Justin thinks it's cool that she is older and hot. She isn't clingy and has her own life," the source added. "There are no bad consequences for Justin to hook up with her. She is very easy going and just makes it fun for him to be around her."

Recently, the 22-year-old Baby singer reportedly tried to rekindle his love with ex-flame Selena Gomez. The two had even liked a photo of each other on Instagram, following which the Same Old Love singer had attended Bieber's concert at the Staples Center in Los Angeles in March. Kourtney had also attended the concert.

Bieber and the 23-year-old reportedly had an argument during the show. "The speculation is that an argument had taken place between the two before the show since he cancelled the date plans," a source previously told EOnline. "Something had shifted Bieber's mood completely."

A few days later, Beiber brought his other ex-flame Hailey Baldwin to the iHeartRadio Music Awards despite knowing that the Come and Get It was present at the show.

A source told HollywoodLife: "Selena in her never-ending back and forth with Justin is now over him again. She doesn't really want to deal with him right now and is now focused on her tour and career. But the way Selena acts tomorrow is going to be a whole new wave length and she will be probably all about him again." The gossip site, however, later added that the former couple are keeping in touch via text messages.

Bieber and Gomez dated from 2010 until early 2015 before parting ways.
