It appears things have heated back up again as a source tells PEOPLE the pair have been "hooking up on and off for a few months now."
Multiple sources confirmed to PEOPLE last year that Bieber, 22, was hooking up with Kardashian, 36. The pair were last seen together in late March following the Los Angeles leg of the pop star's Purpose World Tour.
"They have hooked up a few times, including recently. It happens in L.A," the source shares. "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."
Kardashian has three children – daughter Penelope, 3, and sons Mason, 6, and Reign, 1 – with ex Scott Disick, who vacationed in Vail, Colorado with her family last week.
"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 continues. "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.”
In December a separate source told PEOPLE that Bieber was enjoying a "huge ego boost from hooking up with Kourt," over the span of a "few months."
