Actress Lindsay Lohan's temper was tested after her girlfriend DJ Samantha Ronson reportedly ignored her during a heated lover's quarrel.

The pair refused to speak to one another en route to Washington on Thursday after Lohan spent the train ride complaining of her staff, according to the New York Post.

A source tells the newspaper Lohan shouted at Ronson: "I do what's good for you, not what's best for both of us." Lohan later continued the tongue-lashing, reportedly yelling at Ronson: "Don't f***ing lie to me!" to the dismay of nearby passengers.

Sources add Lohan was "whining incessantly and Samantha was trying to deflect it."
