This duet is just yuge!

Barbra Streisand teamed up with Donald Trump for a good old sing-song Thursday night. Kind of.

Babs joined Jimmy Fallon, who was disguised as the GOP nominee, for their own version of “Anything you can do, I can do better” on “The Tonight Show.”

It quickly got political, though, with Fallon’s Trump character soon switching up the words to suit his own agenda.

“Listen up, Babs. We’re gonna sing this song and it’s gonna be a fantastic song. Together we’re gonna make duets great again,” said Fallon as Trump, before launching into the tune.

Check it out in the clip above.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
