Adele is reportedly in talks to make a duets album with Barbra Streisand.
The 28-year-old singer and the showbiz legend are said to have met in Los Angeles last week to discuss the idea and label bosses at Columbia Records, which they are both signed to, believe they can enjoy great chart success if the plan comes to fruition,
Indeed, the scenario has been likened to Lady Gaga's successful collaboration with Tony Bennett.
An industry insider said: "This could easily become one of the most important and lucrative collaborations in modern music history. And they are both very much up for it.
"Despite the huge gulf in age and their different genres, both have said they would love to get together in the studio and record a duets album.
"The feeling is that the tracks would most likely be new versions of their own best-known numbers with maybe one of two new songs added to the mix."
Although Adele and Streisand are extremely busy, they are said to be very enthusiastic about the idea and are determined to make it happen.
The source told the Daily Star Sunday newspaper: "Both of them have busy schedules but the logistics shouldn't be too much of a problem because this is something they both have their hearts set on."
