Barbra Streisand Dazzles on ‘Tonight Show Starring Jimmy Fallon’: ‘Partners’ Singer Appears For First Time In Over 50 Years [VIDEOS]

Normally we'd say, "Barbra Streisand stopped by the Tonight Show..." but she actually stole the entire episode of last night's Tonight Show Starring Jimmy Fallon.

The appearance was the first one the singer has made on the famed NBC show in over five decades. And not only did she knock the performances (yes, more than one!) out of the park, but she showed the world just how down-to-Earth, and truly funny, she really is.

Fallon introduced the singer in order to give the crowd a little "taste" of the new Partners album, which is available now. But since she didn't have the backing vocals of Elvis Presley, Blake Shelton and Michael Bublé in-house, Fallon had to do a little impersonation work – which was a total win.

Check out the Partners medley between Fallon and Streisand below:

Following their performance, the Tonight Show host invited the legend over to his desk... literally. Streisand took a seat behind the comedian's desk during their interview. During which, the two chatted about the comic's singing and Streisand's impressive non-diva-like qualities.

The next section of the interview was devoted to Streisand's surprisingly normal personality.

"I've got to say, honestly," Fallon began, "I was afraid that you were coming here today. I was afraid that you were going to be more of a nightmare. ... You're the one person who is allowed to be the diva of all divas!"

She then closed the Tonight Show episode with "Come Rain or Come Shine," which is sung with John Mayer on the new album.
