She was 17, a baby, she had baby fat, she wasn't fat by any means lol.
my point making this thread is to prove she was a seasoned performer and had a passion for dance from the start it was her choice to hold back a little on dancing so she could be able to sing without huffing and puffing, this goes to show she was passionate about singing just as much, if you watch bomt video rehearsals she went all out, the original choreo was just as complex and intricate as MATM and Slave, but she removed most of it to balance out singing and dancing, I wish she would implement this method again since she's in the best shape of her life and her voice is still intact, one can dream.
