Tony Bennett has recruited an all-star lineup of singers for his upcoming duets album, including Norah Jones, Lady Gaga, and Amy Winehouse. USA Today and Billboard.com are reporting that the album, 'Tony Bennett: Duets II,' will be released on Sept. 20 and is the follow-up to his 2006 album, 'Duets: An American Classic.'

'Duets II' will celebrate Bennett's 85th birthday and will feature a wide variety of artists from all genres. In addition to those already mentioned, John Mayer, Carrie Underwood, Mariah Carey, Josh Groban, Sheryl Crow, Faith Hill, Willie Nelson, Natalie Cole, k.d. lang and Andrea Bocelli will appear on the iconic singer's 'Duets II.' All of the studio sessions will also be recorded for a documentary, which is also due out this fall.

Fellow crooner Michael Buble will also sing on Bennett's newest duets album, and the 'Hollywood' singer recently spoke about the collaborative effort in an interview. "You're talking about some adult contemporary acts, you're talking about some real pop acts, but ... the correlation between all of us is that we idolize [Bennett]. He's an icon, and he's still doing what he does better than anybody else," Buble says.

It will interesting to see what kinds of sounds emerge from the various duets. We are especially excited to see the return of Amy Winehouse. The 'Rehab' singer hasn't recorded much material since her 2006 Grammy-winning debut album, 'Back in Black.' Stay tuned with PopCrush for more updates on 'Duets II.'
