Celine Dion made a surprise appearance at a Las Vegas benefit concert this week.

The 49-year-old singer performed a version of "My Heart Will Go On" with Steve Aoki at the Hakkasan Group's Vegas Strong show Tuesday.

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.

The fund benefits those affected by the shooting on the Las Vegas strip in October that left 58 dead and hundreds injured.

"'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.

"Since then I've played it across the world and back. I've always wanted to do it live with the queen herself & when we mentioned the #VegasStrong charity event she was down!"

Dion has been in residence at The Colosseum at Caesars Palace in Las Vegas since 2011, and will perform into 2018.
