Kenneth "Babyface" Edmonds, who is co-producing the album, told Billboard that the album was almost complete, adding, "It's a beautiful, beautiful record. She's singing amazingly well, and it's been a fun project to do."
A posthumous duet with Elvis is also expected to be part of the record.
It was previously reported that Willie Nelson, Usher, Robin Thicke, Lionel Richie, Yo Yo Ma, Stevie Wonder, Lady Gaga, Bette Midler, Andrea Bocelli and Beyoncé were among the artists who would sing with Streisand.
The multi-award-winning performer has yet to officially confirm the talent that will be featured on the album. Earlier this year her representatives confirmed that the album was underway.
Streisand's first "Duets" album featured new and existing duets with Celine Dion, Ray Charles, Barry Gibb, Judy Garland, Donna Summer, Frank Sinatra, Barry Manilow, Michael Crawford, Josh Groban and more. Her recent albums include "Release Me" and the live album of her Back to Brooklyn concerts. Streisand is an artist in multiple disciplines.
