KANYE WEST went after a FEMALE photographer Sunday night in Miami . . . after she asked about KIM KARDASHIAN'S ex-boyfriend REGGIE BUSH.
--Kim is in the city filming "Kourtney and Kim Take Miami" . . . and she and Kanye had just left a dinner date at a place called Prime 112. Apparently, Reggie and his pregnant girlfriend just happened to be at the same restaurant.
--The woman approached them outside the place and said, quote, "Kim did you know Reggie is here having dinner? Did you wanna go congratulate him on his pregnancy?"
--That's when Kanye lunged. He didn't try to hurt the woman, but he grabbed for her camera. Kim was smiling during much of the confrontation. Then she and Kanye left in a Rolls Royce.
