Gwyneth Paltrow iced her best-friendship with Madonna when a Brit mag asked her to name her two closest galpals -- and she chirped: "Stella McCartney and Princess Rosario of Bulgaria." When Madonna read the piece, she phoned and demanded to know why she'd fallen from grace. Gwyneth sighed and replied, "You're too bossy!" She thanked Madonna for pushing her to stop smoking cigarettes -- but accused her of coming on like a steamroller about everything! Stunned, Madonna promised to chill, but . . . don't bet on it.
