Brunch turned into a crazy chick fight -- busted up by cops -- during the launch party for a reality show called, "Rica, Famosa, Latina" ... and TMZ got the wild video.
Bev Hills PD responded to the Luxe Hotel when cast members started throwing punches, pulling hair and tearing off each other's clothes last Saturday. Several people suffered minor injuries, and one went to a hospital.
The show -- set to premiere Sept. 16th -- is sort of a Latin version of "Real Housewives of Beverly Hills" and is produced by ex-'Housewife' Joyce Giraud ... which means, even though she may not condone it, she knows the game: a good catfight before a premiere is good for business.
'RFL' follows late singer Jenni Rivera's sister and several other wealthy Latinas ... who have awesomely adopted a Three Stooges style of fighting.
