Nick Jonas Sings "I'll Be Home For Christmas" A Cappella, Melts Hearts Instantly

Nick Jonas posted a new video on his Facebook page this week, in which he sings an a cappella version of the classic holiday song "I'll Be Home For Christmas." The video shows Nick Jonas strolling through an NYC park singing to himself, and it's so sweet, heartwarming, and excellent all at once. Nick already blew us away with a video last week, where he performed "Jealous" on FAO Schwarz's giant piano. This one might take the cake, though. Watch the video above, and then take a look at all these hot pictures of Nick Jonas through the years.
