Pop superstar Lady Gaga donned a tuxedo and a bowler hat to channel Frank Sinatra for a Grammy tribute show marking 100 years since his birth.

The Bad Romance star slicked back her hair to complete her masculine look for her performance at the Sinatra 100: An All-Star Grammy Concert in Las Vegas on Wednesday (02Dec15).

Lady Gaga gave a rendition of Sinatra's ode to her hometown, New York, New York, during the star-studded gala show, which was held at the Wynn Las Vegas Encore Theater and hosted by funnyman Seth MacFarlane.

Usher kicked off the show with a performance of That's Life, and other stars who took to the stage included Las Vegas regular Celine Dion, who sang All the Way, and Alicia Keys, who belted out I've Got a Crush on You.

Carrie Underwood, Adam Levine, Tony Bennett and Quincy Jones all took part in the gig before Lady Gaga closed the show, and Sam Smith and U2 contributed video messages.

After the concert, Lady Gaga tweeted a picture of herself in costume and added, "Happy Birthday Frank".

The concert will be televised on 6 December (15), less than a week before what would have been Sinatra's birthday on 12 December (15).
