Goldblum's New Chick 35 Years Younger

Jeff Goldblum, 56, scored himself a new GF -- one who was barely a fetus when "Earth Girls Are Easy" came out.

The girl is 21-year-old Tania Raymonde, who played Ben's daughter on "Lost" ... and probably gets confused for Jeff's daughter whenever they go out.
