Beyonce -- Honors Trayvon Martin ... Following Not Guilty Verdict

Beyonce interrupted her own concert last night to take a moment of silence for Trayvon Martin ... right after news broke that jurors found his shooter, George Zimmerman, not guilty.

It happened at Bey's Nashville concert Saturday. About 30 minutes before the singer took the stage, news broke that Zimmerman was acquitted of both the 2nd degree murder charge and manslaughter charge in the shooting death of 17-year-old Trayvon.
