The 74-year-old entertainment icon released a video to her official Vevo page on Friday, in which she sings "At the Ballet" from A Chorus Line with a little help from her famous pals, Anne Hathaway and Daisy Ridley.
The video shows behind-the-scenes footage of Streisand, Ridley and Hathaway (who was very pregnant with her first child, son Jonathan, at the time) belting out the lyrics to the classic tune. The song is part of Streisand's upcoming album, Encore: Movie Partners Sing Broadway, and was recorded inside her Malibu, California, home studio.
"I wanted to work with some women on this album, and I thought, 'Well, give them a little character, have them act [out] scenes,'" Streisand explains. "So, I have to have good actresses who can sing."
"Anne Hathaway was perfect casting for the role of Maggie," she adds. "When Anne came into the studio, I was so happy to see her looking radiant and glowing -- no makeup, with the beauty of a woman about to give birth to a child."
While Streisand was well aware Hathaway had incredible pipes (in case you need proof, just watch the 33-year-old actress' Oscar-winning Les Miserables performance), she wasn't so sure about Ridley. Streisand admits she "took a chance" with the Stars Wars: The Force Awakens star.
"I was interviewing Daisy Ridley for Gypsy, and I said, 'Can you sing?'" Streisand reveals. "And she said, 'Yeah, I can sing.' I didn't know whether that was supposed to be like me in Funny Girl, when he says, 'Can you skate?' and I go, 'Of course I can skate!' and then the next minute she's falling all over the place because of course she can't skate."
Turns out, Ridley wasn't kidding -- she really can sing!
"I have had no experience recording," Ridley, 24, admits in the video. "So, to have my first recording experience with Barbra Streisand is pretty insane. Not only am I working with two Oscar-winning actresses, both of those actresses won Oscars for musical films, so, slightly daunting."

The album, which is currently available for pre-order on iTunes and Amazon, also features duets with Alec Baldwin, Chris Pine, Seth MacFarlane, Hugh Jackman, Jamie Foxx and Antonio Banderas.
Streisand is gearing up for the 70th Tony Awards on Sunday, marking her first appearance at the star-studded show in 46 years. Host James Corden recently joked that he has big plans for the legendary singer.
"I thought, 'Why don't we have a big, sort of karaoke-type sing-along in the Beacon theater?' Because there's all these incredibly talented people in there," the Late Late Show host explained during a sit-down interview with Seth Meyers. "So I might go out and give them some drinks and then see if I can get, like, Barbra Streisand to sing something."
