Danielle Bregoli Breaks Down Over XXXTentacion's Murder

Danielle Bregoli is still taking the news of XXXTentacion's murder hard, and pleading for the violence to end.

We got Bregoli downtown L.A. -- on the set of her music video "Trust Me" with Ty Dolla $ign -- where she shed tears over XXX's murder, which Bregoli says needs to be a wake-up call for others like Tekashi69 and Trippie Red who act all big and tough.

Bregoli and XXXTentacion were good friends apparently ... something people didn't really know 'til Danielle shared a video Monday of a phone call she recorded with the late rapper. In the call, XXX apologized about something, although Danielle didn't elaborate on it.
