Frankie Sandford battled homesickness in LA while filming her band's new reality show.
The singer is seen breaking down in tears in the show, shortly after moving with her Saturdays bandmates into a LA mansion, The Sun reported.
"I'm hoping I am strong enough to get over it. I felt really homesick," she says in another episode.
Audiences will see Frankie, who checked into rehab for depression in 2011, crying alone in her bedroom and talking to the camera about her battle with mental health problems in the past.
The Saturdays' reality show is an attempt by the girls - Una Healy, mum-to-be Rochelle Humes, Vanessa White, Mollie King and Frankie - to make it big in the US.
But producers of the E! reality TV show, Chasing The Saturdays, had to add subtitles to some of the scenes, the newspaper said, so US viewers could understand them.
