  • 9 years ago
The 19th annual Jingle Ball concert rocks New York.

Artists like Charli XCX, Maroon 5, Ariana Grande, Sam Smith and OneRepublic wowed the sold-out crowd.

Pharrell put on his happy face before being joined by "The Voice" co-star, Gwen Stefani.

Meghan Trainor brought her bass along for good measure …

… and Taylor Swift donned an appropriately festive outfit.

The event is part of the national iHeartRadio Jingle Ball Tour held around the U.S.

And proceeds benefit the Ryan Seacrest Foundation, which uses entertainment to help inspire children.
