Give the kids in this video about 30 seconds to really get into Zac Brown Band's 'Chicken Fried.' The boy, whose name might be Ty, is eager to sing along, but it takes some prodding to get little sister to join him. She's obviously very fond of big bro, and when she jumps on board for the duet, it's nothing short of special. 

But then the little tyke grows weary of her older brother and begins to demand more camera time. Is she a diva in waiting? Likely not. She appears to be all of two years old, so a short attention span and random fits of fussiness are to be expected. Both kids are adorable from start to finish.
