Chris Brown's blossoming friendship with Scott Disick could be growing more complicated.

According to Hollywood Life, Disick is now pressuring the "Loyal" singer to take a side in his growing feud with Justin Bieber. Word is the 32-year-old Disick has been talking to Brown nonstop about Bieber, now rumored to be hooking up with Disick's ex-girlfriend Kourtney Kardashian.

"Chris is caught in the middle of Scott's hatred toward Justin Bieber," a source said. "He hates being in this position. All Chris wants to do is celebrate his 'Royalty' album and talk about his daughter and have a good time, and Scott's ruining the vibe."

Brown recently featured Disick in his "Picture Me Rollin" video. But the singer is rumored to be just as cool with Bieber, leading sources to speculate he's not about to allow himself to be dragged into the middle of the drama over Kardashian.

Disick and Kardashian, the mother of his three young children, split earlier this year, after he was spied openly cavorting with ex-girlfriend Chloe Bartoli in Monaco over the July Fourth holiday weekend. Since then, he has also been romantically linked to teenage model Lindsay Vrckovnik, and the two spent several weeks together partying from coast to coast.

Kardashian is rumored to have not at all been impressed by Disick's appearance in Brown's video and has gone as far as to label it a joke. Word is all her sisters agree with her harsh assessment and "are all laughing at Scott over this video."

Ditto for Bieber, who yet another source indicates "can't stop laughing" at how out of place Disick looks in his cameo.

"Scott's the running joke between Justin and his crew," a source added.

Over the last several weeks, the 36-year-old Kardashian has been spotted hanging out Bieber. She was recently seen leaving his residence in the early hours of the morning.
