New details are emerging about the lineup of Tony Bennett's upcoming album, 'Duets II.' Not only has Carrie Underwood been given the honor of singing with the legend, so have Faith Hill and Willie Nelson.

In 2006, Bennett released 'Duets: An American Classic' with musicians from all genres including Tim McGraw and the Dixie Chicks. 'Duets II,' will include songs from the 30s as well as jazz standards like Billie Holiday's 'Stranger in Paradise.'

'Duets II' is being recorded to celebrate Bennett’s 85th birthday on August 3. Other artists taking part include Mariah Carey, Josh Groban, Amy Winehouse, Lady Gaga, Michael Buble, John Mayer, Sheryl Crow, Norah Jones, Natalie Cole and Andrea Bocelli.

The studio sessions with each artist are being filmed for a documentary and that will be out sometime this fall. The album will be released on Columbia Records and will hit stores on September 20. Stay tuned with Taste of Country for more updates on the album.
