Blake Shelton and Barbra Streisand make an unlikely pair. She's a mezzo-soprano with an acclaimed pop career, while he's a country singer and farm boy at heart. However, despite first impressions, the talented two teamed up for a duet -- and it's beautiful.

'I'd Want It to be You' appears on Streisand's upcoming album 'Partners.' It's a ballad-driven love song with a few witty lyrics hat will have fans smiling.

One of the sweetest parts of the songs happens when Streisand sings, "You're still sweet as a honeybee after all these years," and Shelton retorts, "You'll always be that funny girl to me," prompting a laugh from his duet partner. It's a nod to her acting career and appearance in the 1968 romantic comedy 'Funny Girl.'

Who else is on the record? Streisand announced her partners on the project, including the late Elvis Presley, John Legend, her son Jason Gould, Andrea Bocelli, Michael Bublé, Babyface, Josh Groban, Billy Joel, John Mayer, Lionel Richie and Stevie Wonder.

"What an extraordinary collection of talent," the icon shares.
