It seems that the hit was performed without Dion’s consent, which led to a statement being issued by her record label on her behalf:
“Today, Celine Dion’s management team and her record label, Sony Music Entertainment Canada Inc, were informed of the unauthorized use of the video, recording, musical performance,
and likeness of Celine Dion singing “My Heart Will Go On” at a Donald Trump / JD Vance campaign rally in Montana.” “This use is not authorized, and Celine Dion does not support it or any similar use.”
