Justin Bieber keeps warm in a denim jacket as he stops by the observation deck at The Empire State Building in New York City on Friday (November 18).

The 17-year-old musician teamed up with the Marine Corps to encourage fans everywhere to donate to Toys For Tots to help make sure no child is forgotten this holiday season.

After switching on the lights, Justin headed over to the SiriusXM Studio to chat about his new holiday album, Under The Mistletoe and more.
