Lady Gaga will honor her friend and collaborator Tony Bennett at a concert celebrating the jazz legend's 90th birthday. The two-hour show will air on December 20th on NBC, the network announced Tuesday. Other performers include Aretha Franklin, Andrea Bocelli, Billy Joel, Elton John, Michael Bublé, Diana Krall, Rufus Wainwright, k.d. lang, and Stevie Wonder.

Gaga and Bennett first collaborated in 2011 on his Grammy-winning album Duets II, on which Gaga sang "The Lady Is A Tramp." Three years later, the two released on Cheek to Cheek, a collection of jazz standards from the The Great American Songbook. The album has been a massive success for the duo, reaching top ten in over 20 countries and receiving glorious reviews from jazz critics. When the album debuted atop the Billboard 200, Gaga became the first female artist of the decade to have three number-one albums, while Tony extended his record as the oldest person to reach the top spot on the chart. The album also earned Lady Gaga her sixth Grammy, making her the only musician in history to win the award for both dance and jazz music.

In June, Bennett announced that a follow-up to Cheek to Cheek would be out later this year, however, we're hearing that the project has been pushed back to let Gaga focus on her upcoming solo album.
