Natalie Holer can actually sing live, so its okay if she lip syncs some performances. it can be hard to sing such a fast vocally demanding song live while moving and dancing
god it has to be hot in there.. with all those people dancing and then the flames o.o dang girl you werent joking when you said youd turn up the heat lmao
She's not completely lipsyncing, you can actually hear the backup track and her voice... she actually goes a tiny bit flat on a few notes, not enough to mess up the song, but enough to show she's not /completely/ cheating :) Nice song though
She does look like shes lip sync'n, however with high performance entertainment like this its not surprising. the level of fitness an individual would have to have to dance for a full set and sing without sound like your out of breath is up there....
