Barbra Streisand and Jimmy Fallon sing medley of duets on Tonight Show (VIDEO)

Barbra Streisand sang a medley of duets with Jimmy Fallon on The Tonight Show on Monday, September 15, 2014. The songs were from her album 'Partners' with Jimmy standing in for Elvis Presley, Blake Shelton and Michael Buble.

This was so awesome live. I didn't know Jimmy Fallon could do this. I'm impressed.

Living legend Barbra Streisand looks amazing. She's 72 years old. Her plastic surgeon did a great job. It looks like she hasn't aged, though she probably instructed the show not to do closeups and only these almost full body shots of her.

Also, I love how Barbra clearly favors the left side of her face. What's wrong with the other side? Anyone know? But whatever it is -- always show your good side.

This was Barbra's first appearance on The Tonight Show starring Jimmy Fallon.
