Reese Witherspoon turned heads in a lace minidress at a benefit for EIF's Women's Cancer Research Fund in Beverly Hills Wednesday night, one of her first red carpet appearances since splitting from Jake Gyllenhaal around Thanksgiving. The Daily Mail credits the "heartbreak diet" for her slim shape.

Also attending was newly-single Taylor Swift, who broke up with Taylor Lautner last month.
