Celine Dion made a surprise appearance at a Las Vegas benefit concert this week.
Dion, who wore a sparkling one-shoulder jumpsuit, hugged Aoki before launching into the "Titanic" ballad.
Aoki, a DJ and musician, danced with the singer after transforming the end of the song into a club anthem remix.
The Vegas Strong concert raised over $1 million for the Las Vegas Victims Fund, according to Us Weekly.
"'Our Hearts Will Go On' - Celine #VegasStrong #HakkasanGroup #BenefitConcert #LasVegas #CelineDion #CelineDionVegas #SteveAoki," Dion captioned photos from the show Wednesday on Instagram.
"Two summers ago I made a remix to My Heart Will Go On and debuted it @Tomorrowland," Aoki wrote on his own account.
Dion has been in residence at The Colosseum at Caesars Palace in Las Vegas since 2011, and will perform into 2018.
