Chris Brown Accuser -- No Stranger To Celeb Beef ... Railed On Jason Derulo

The woman who has accused Chris Brown of punching her in the eye has had run-ins with celebrities before ... with the likes of Jason Derulo.

Liziane Gutierrez was enraged at Derulo back in August when she claims he ditched her as he left The Argyle in Hollywood. TMZ shot this video outside the club of Liziane ranting that Jason had flown her from Vegas to be with him for the night and for some reason left her high and dry.

Our Derulo sources told us at the time Liziane was delusional ... he didn't know her from Adam.
