Lady Gaga and Tony Bennett announced a New Year's Eve concert in Las Vegas.

The duo, who released the jazz duets album 'Cheek to Cheek' recently, will play the The Cosmopolitan casino.

It will be their first collaborative gig in the US since the release of the record.

Gaga said in a statement: "I can't wait to kick off 2015 'cheek to cheek' with the legendary Mr. Tony Bennett. New Year's celebrations are about cherishing family, friendship, and the future - three things this man has taught me much about."

The Cosmopolitan's chief marketing officer, Lisa Marchese, added: "We wanted to one-up ourselves for what people can expect. It's such an unexpected mashup - you just want to see it."

Tickets will go on sale from Friday (October 10).
