Partners features Streisand duetting with an all-male hit parade of singers, including Stevie Wonder, Michael Buble, Blake Shelton, Billy Joel and Lionel Richie.
If Partners hits No. 1, it will make Streisand the first artist with No. 1s in each of the past six decades ('60s through '10s), and it would extend her lead as the female artist with the most No. 1 albums.
To promote the new album, Streisand made a well-publicized visit to NBC's The Tonight Show on Monday, where she was the only guest for the evening. She performed a medley of songs with host Jimmy Fallon, chatted and then sang a solo number at the end of the show. It was her first proper appearance on a late-night talk show since 1963, when she was last on The Tonight Show.
On Tuesday, she performed on ABC's Good Morning America and is scheduled to appear on ABC's The View on Thursday.
The second-highest new entry on next week's Billboard 200 chart will likely be Chris Brown's next studio effort, X. It may sell around 130,000 copies and come in at No. 2.
