"It sounds so trite, but my private life is mine"

In this quote, Portia de Rossi is expressing her desire for privacy in her individual life. She acknowledges that this belief may seem cliché or overused, however it holds true for her. She values her privacy and wants to keep her individual life separate from her public persona. This could be due to the constant examination and intrusion of privacy that comes with being a public figure. De Rossi is asserting her right to keep specific aspects of her life to herself, far from the prying eyes of the media and the general public. She is setting boundaries and asserting her autonomy over her own life.
