Tony Bennett is at it again.  He's following up his 2006 "Duets: An American Classic" album with another one in the works and he's lined up a bunch of stars to join him.  Michael Buble is one of them.  So who else will be singing with Tony? 

Carrie Underwood, Lady Gaga, Amy Winehouse, Josh Groban, Faith Hill, Norah Jones, Willie Nelson, K.D.Lang and Andrea Bocelli will collaborate with Tony Bennett on his next duets album.  It's going to be called "Tony Bennett: Duets II."  Michael Buble is thrilled to be a part of it and says all of the singers on the album idolize Tony.  Michael calls Tony an icon and says "he's still doing what he does better than anybody else."  The album comes out September 20th.
