R & B Star Jeremih -- VIDEO of Beer Brawl at Fuddruckers

We just got video of R & B singer Jeremih and his crew throwing beer bottles in a Fuddruckers, and he sure looks like an out-of-control punk.

Jeremih claimed the manager was racist by asking him to leave the area around the front counter. The manager tells us Jeremih and his guys were harassing a young female cashier and she told the manager they were making her feel uncomfortable.

When you watch the video ... you see the bottles fly, and whatever was said just doesn't justify it.

Cops have made no arrests.
