Jimmy Fallon is known for getting his guests to do some strange things. From his "Lip Sync Battles" to his "Wheel of Impressions" game, his show is full of nonsensical moments that make our favorite celebs feel more like real people and less like these statuesque gods.

Fallon recently took his games to the streets of New York, or more specifically to the subway station under New York, with a special guest. However, they made sure to disguise themselves until they were basically unrecognizable and then they performed a concert.

He was joined by 90s pop star and iconic diva Christina Aguilera. The two of them took on a kind of boho-inspired look with some hats, some wigs, and some denim, and of course some big sunglasses.

But here's the thing, no amount of floppy hats can disguise Aguilera's voice. It's truly one of a kind, and even if you can't see her face, you know it's her.

The pair belted out Aretha Franklin's classic song "Think" with Jimmy playing a Banjo, and somehow it worked.

Literally as soon as they started to perform people were gathering around with their phones, taking a bunch of videos and pictures. There are literally videos of people rushing over to try and see them.

Honestly, there's no way they don't know that it's Aguilera.

Fallon and Aguilera then take off their wigs and sun glasses and go into Aguilera's hit song "Stronger."

She's absolutely belting it out while Fallon is running around with the cowbell and it's just so impressive.

It's almost unfair how talented she is. It seems like it's effortless for her to just jump into the big epic songs and the things she can do with her voice are honestly just baffling to me.

When they got back to the studio for the episode of The Tonight Show, Aguilera performed one of her new songs, "Fall in Line" off her new album Liberation.

She's going on tour starting in September, so if you want to check it out you should start looking for tickets pretty soon!

Hopefully she will perform some of her classic 90s hits that we all still sing in our cars when no one's looking. (I'm not the only one who does that right?)

It's nice to have Christina Aguilera back with new music, and her new transformation has really managed to take the world by storm. It's so amazing to see how incredible she really is.

As for Jimmy Fallon, he keeps doing great things with his show, making us laugh every night, but he also has a lot of heart and proved that with what he did for the Parkland students.
