Lady Gaga and Tony Bennett are set to take the stage at The Cosmopolitan casino on New Year's Eve for their first show together in the US since they released a joint album late September.
The Las Vegas Strip resort announced Monday that the 28-year-old pop superstar and the 88-year-old jazz crooner will ring in the new year with jazz standards from their album Cheek to Cheek.
"I can't wait to kick off 2015 'cheek to cheek' with the legendary Mr Tony Bennett," Lady Gaga said in a statement. "New Year's celebrations are about cherishing family, friendship, and the future - three things this man has taught me much about."
Tickets for the show go on sale Friday.
Las Vegas welcomes more than 300,000 visitors each New Year's Eve holiday, and casinos step up with top-tier music acts, world-renowned DJs and an elaborate fireworks show.
Bringing in Bennett and Lady Gaga is an effort to distinguish the resort during a highly competitive time in the market, according to The Cosmopolitan's chief marketing officer, Lisa Marchese.

"We wanted to one-up ourselves for what people can expect," she said. "It's such an unexpected mashup - you just want to see it."
