The career behind the tributes
ITV's September 2021 career account traced Sarah Harding's rise through Popstars: The Rivals to Girls Aloud.

ITV also recalled Harding's acting and other television appearances.

ITV reported on September 5, 2021 that Harding had died at 39, following her public disclosure of breast cancer. Its coverage included tributes to her energy and presence. This remembrance preserves that date without speculating about private treatment decisions or turning one person's experience into medical advice.
