The All Fired Up hitmakers invited a camera crew to record their mission to find fame in America last year (12), and the series, Chasing The Saturdays, will premiere on Tv later this month (Jan13).
In the debut episode, Sandford, who checked into a clinic in 2011 to treat depression, is seen crying alone in her bedroom - and she admitted she was struggling to deal with the big move from her native U.K.
She says, "I'm hoping I am strong enough to get over it. I felt really homesick. I am such a baby - when I walked in it felt empty."
