Beyoncé is honoring a man who was stabbed to death -- allegedly because he was dancing to her music in public -- and she's doing it a heartfelt message on one of her biggest platforms.
The singer paid tribute to 28-year-old O'Shae Sibley on her website, with a message that reads ... "Rest In Power O'Shae Sibley." It's the first thing you see when you go to beyonce.com, where it's prominently displayed on the homepage.
Sibley was fatally stabbed over the weekend at a Brooklyn gas station after getting into a scuffle with another man ... and cops are reportedly investigating the incident as a possible hate crime.
Sibley was gay and leading up to the confrontation, witnesses say he was voguing in the parking lot to Beyoncé's tracks. Authorities think the altercation might have started because the suspect was reacting to Sibley dancing, according to the NY Post.
Part of the face-off was actually captured by a surveillance camera outside ... and you can see quite a few people arguing.
The actual stabbing happens off-camera, but you can see Sibley (who's shirtless and wearing a hat) and a friend getting heated with an opposing group. Eventually, Sibley goes around a corner ... and moments later you see him come back into frame.
One of his pals who was there on the scene that night posted bloody photos of the aftermath, claiming the attacker was Muslim and let them know he didn't like gay people.
Obviously, an investigation is ongoing -- and the suspect is still on the loose -- but Sibley's story has already struck a nerve with Beyoncé.
