Nick Jonas Sings Christmas Carols at Children’s Hospital [PHOTOS]

Nothing warms our hearts more than seeing celebrities give back, especially during the holiday season. Nick Jonas recently made the day for dozens of children at Toronto's Sick Kids Hospital, visiting with patients and even singing Christmas carols with the choir.

According to Pacific Coast News, the 'Jealous' singer partnered with Duracell and came to the hospital to give away toys and batteries to the sweet kids. He also posed for pics with the patients, as well as serenaded them with festive songs -- even a few of his own hits.

Check out the sweet photos of Nick visiting with patients below.
