Nick Jonas treated subway riders to an unexpected concert over the weekend.

The 22-year-old musician serenaded travelers at the West 4^th subway station in Manhattan.

A fan named Jocelyn tweeted a photo of Jonas giving the impromptu performance on the platform. She captioned the pic, "i hate it when i'm just trying to get to my subway and nick jonas is singing. SO annoying."

Jonas was bundled up for the cold weather as he strummed his guitar, wearing a leather jacket, knit scarf and hat.

The former Jonas Brother singer was joined by another musician, who played guitar alongside the star.

It's been a couple days for Nick, who appeared an interesting mix of events.

On Friday, Jonas invited fans to join him at Lucky Strike bowling alley in New York City.

Then on Saturday, the "Jealous" crooner performed at the 2014 Nickelodeon Halo Awards. Afterward, he had a little chat with former President Bill Clinton and his wife, former Secretary of State Hillary Clinton.

Jonas posted a photo of the cool moment to Instagram, crediting the photographer, "Glee" star Darren Criss.

"Post performance chat with the prez and Madame secretary thanks Darren Criss for the photo," wrote Nick.

Over the weekend, Jonas also released a gospel version of his hit single "Jealous." The music star tweeted a video of the new rendition, for which he was accompanied by a very impressive gospel choir.

Jonas took the word "hellish" out of his lyrics to make the song church friendly. The new version was met with a lot of love on Twitter, with many fans posting about the video.

As the new week rolled around, Jonas took to Twitter again, writing, "Whats up Monday."

We're guessing Nick has no intention of slowing down anytime soon.
