The magazine described her as the contestant "who bared calm resolve and tanned hip bones in beating out almost 10,000 girls for the chance at singing and strutting in a P.iddy–steered girl group". O'Day expressed anxiety about competing to be in the group. "I’ve been in the ‘cut’ situation several times," she stated.
