Lady Gaga and Celine Dion have been added to a Grammy tribute to Frank Sinatra.

The ladies will join Zac Brown and Harry Connick, Jr. among other stars, at the Sinatra 100 - An All-Star Grammy Concert to be held at the Wynn Las Vegas on 2 December (15).

The tribute, which will also feature Sinatra's protege Tony Bennett, Adam Levine and Alicia Keys, will air four days later (06Dec15).

Thrilled to be part of the show, Celine Dion says, "I've been singing Frank Sinatra songs in my shows for many years. His voice has been such an inspiration for me and it will always be."

"My grandfather introduced me to Frank Sinatra," Keys adds. "I love hearing his songs, the phrasing, the innocence - the subtle depth that knocks you out when you concentrate on the lyrics. And those arrangements! It brings me back to the lost art of 'the gentleman'."
