March 10 2016, Updated 10:14 a.m. ET
RadarOnline.com has exclusively learned unlikely couple Kourtney Kardashian and Justin Bieber's booty calls are still going strong!
"Justin's learned to keep his mouth shut, because Kourtney made it clear she needs this to be discreet for the sake of her kids as well as the complicated situation that's going on with Scott Disick," an insider revealed.
As RadarOnline.com reported, Kardashian and Bieber recently partied together in L.A, and the reality star was spotted sneaking out of his hotel suite at 4 a.m.
Despite the booty calls being back on, Kardashian is struggling to come to grips with the end of her relationship to her baby daddy Disick, who just returned from a debauched vacation partying in Mexico with a bevy of women.
But 36-year-old Kardashian's ex in the picture is no problem for Bieber, 22.
"That suits Biebs just fine," insisted the insider.
The reason? "He says Kourtney's the best lover he's ever had and he can't stay away from her," said the insider.
As for Bieber's other lovers, like Hailey Baldwin, the insider noted that the "Sorry" singer is "obviously still stringing her along and there's nothing long term in the cards."
Anyway, added the source of Kardashian and Bieber, "He loves having an older, experienced lover and they have a great friendship connection, too, so it works for both of them."
