The shows will go on in Las Vegas, two days after the worst mass shooting in modern U.S. history.

Celine Dion and Wayne Newton were scheduled to return to their respective Sin City stages Tuesday night, as were Osmond brother-and-sister duo, Donny and Marie.

A representative for the Canadian diva said Dion’s shows at The Colosseum at Caesars Palace remain as scheduled.

“Praying for all the innocent victims and their families in Las Vegas,” Dion tweeted following Sunday night's tragedy.

Donny and Marie, as well as “Mr. Vegas,” Wayne Newton, were also expected to perform Tuesday evening.

But Jennifer Lopez, whose “All I Have” show was scheduled at the Planet Hollywood Resort & Casino, postponed her performance out of respect for the victims and their families, a spokesperson said.
